What is premature birth?
The definition of a 'premature' or 'preterm' baby is one that is born before 37 weeks. There are different categories levels of prematurity and these carry their own risks:
- Extremely preterm (less than 28 weeks)
- very preterm (28 to 32 weeks)
- moderate to late preterm (32 to 37 weeks).
What are the symptoms of premature birth?
The following symptoms before 37 weeks of pregnancy could be signs that you are about to go into labour:
- an increase in pelvic pressure within the vagina or rectum.
- an increase in discharge and/or a gush/repeat trickling of fluid, which could mean your waters have broken (preterm premature rupture of membranes).
- bleeding or losing your mucus plug.
- period type pains in your abdomen or lower back. These may have a rhythm or be constant.
If you have these symptoms contact your hospital.
What is the treatment for premature birth?
If a pregnancy is found to be at high risk of premature birth, the mother is treated to extend the pregnancy as far as possible. There are various ways this is done.
How common is premature birth?
In the UK, around 60,000 babies are born prematurely each year. The rate of preterm birth is between 7-8% across the UK.

What are the causes of premature birth?
In some cases a cause of preterm birth can be shown but more often it is unknown or unclear. Complications, such as infection or cervical incompetence increase the risk. Women who are having a multiple pregnancy (twins, triplets or more) are also have a higher chance of giving birth prematurely. The average length of pregnancy for twins is 37 weeks, and 33 weeks for triplets.
In 25% of preterm births, the delivery is planned because the mother and/or baby are suffering life-threatening complications such as pre-eclampsia, kidney disease or growth restriction.
Why is premature birth a problem?
During the nine months of pregnancy babies' bodies are developing in the womb to allow them to survive and thrive when they are born. When a baby is born too soon, some parts of their development will not have been finished and this means they are not ready for life outside the womb.
Luckily advances in neonatal care have come on greatly and neonatal units, special care units and paediatricians are equipped to support the baby until their bodies strengthen and develop fully.
However, the earlier a baby is born the higher the risk is of health problems. There are different levels of prematurity, and generally the risk increases the earlier the birth is - babies at highest risk are those born before week 26.
Most preterm babies arrive early without warning. However, some pregnancies are known to be at risk of ending in preterm birth.
Giving birth is one of the most life-changing experiences you'll ever have, but it doesn't always go as planned, especially when your baby is premature.
If your baby is born prematurely, she may need to spend some time in hospital.
Being told you are at risk of premature birth can be shocking and distressing.
It's not always possible to explain the causes of preterm birth and why it happens. There are risk factors for being born early, such as infection, placental problems or genetic problems, but in many cases the cause is unknown.
Staying emotionally strong for your premature baby is all about looking after yourself as well as them.

I didn’t catch infection immediately and I was on antibiotics for 7 days.. now i am in my 23 weeks and I have got E coli infection in vagina for which I am getting antibiotic dose. I want to know if this infection itself can lead to worse situation for me? Also, due to no water around baby can there be health issues for the baby or myself if we continue to wait?

I am 35+5 weeks pregnant. I had a scan when I was 35+ 1, which showed that the baby's growth slowed down significantly. She is 3.6 centile and her weight is 4lbs 4onz.
I am a small person myself. My weight before pregnancy was 49kg, currently I am 57.2kg. I suffer from IBS. Not taking any medication, but struggle to put on weight. I had to go abroad for 4 weeks, and I stopped gaining weight at that time (30-34 weeks pregnant). After the scan that showed growth problem, I saw a consultant who made a plan and advised to monitor the baby until I am 37 weeks pregnant and then induce the labour. Had Torch blood test (no results yet), CTG monitoring done twice (both fine). I am feeling fine. No medical problems apart from IBS. Had another scan with a different consultant tday (35+4 weeks pregnat), which did not showed much improvement in growth (baby gained 50grams), but the 2nd growth scan was done only 4 days after the 1st one. The consultant said that in his opinion I should have a c-section this fri when I am 36 weeks. I am devastated and confused. Two different opinions and recommendations. I have to add that I am a almost 42 years old. This is my first pregnancy. Baby's movements are fine though the only thing that changed is her movements pattern. She has been very active as soon as I lie down and trying to sleep, not that active during the day. I agreed to have a c-section, as the consultant said the baby may become distressed if I try to have a natural induced labour. I also have strep b infection (swab test result). I have doubts regarding c section and not sure whether this is the right decision. Shall I change my mind and wait until I am 37 weeks???? Should I try to deliver naturally??

My baby was born in 32 Weeks 4 days gestation. He was earlier diagnosed with Single Umbilical Artery. Baby was in breach position. Mother's amniotic fluid was nearly Zero with in an hour and doctor had to operate. It has been 1 month in NICU. Baby is not able to suck or swallow and is secreting lot of fluid which had to be removed by suction. My question is it developmental issue or there can be any other issues.

If you are having water leaking and this is on going then I would advise for you to ring the maternity unit if you haven't already to be reviewed.

Hi I live in Newcastle-under-Lyme, Staffordshire, I am a paediatric nurse by background and currently work within the childrens centres and have set up a premature baby support group in Newcastle and Staffordshire Moorlands and wondered if you would be able to place it on your page to let parents know about the service. It is free and open to all who have had premature babies or those who had health issues after birth too.
By Midwife @Tommys on 1 Aug 2018 - 09:30
I will speak to the media team to see if this is possible, but for now, your post will be visible here for people to see and access your wonderful support group if they feel ready to. What a wonderful service, i hope it goes from strength to strength.

I delivered at 36 weeks and my baby is facing shortest of blood. Transfusion was d best bet and I accepted but the blood is still dropping even with d supplements that prescribed by a Pediatric doctor. I want to know, Can I introduce formula to d baby? Will that help? Will I continue to transfuse? When will this end?
By Midwife @Tommys on 23 Apr 2018 - 14:53
Hi Elsy, So sorry to hear that your baby is unwell. I am assuming that your baby is still in hospital under the care of the paediatricians. This can be very stressful for a new mother and if you need any extra support please don't hesitate to contact us. There is no benefit in introducing formula and many units are keen for the very young babies to be breast fed for as long as possible. Ask the doctors as many questions as you need to help you understand what treatments are being used. We wish you all the best. Tommy's midwives x

Hi, I was admitted to labour ward at 27 weeks due to contractions, I tested positive for Fibronectin and given the steroid injections and magnesium. The contractions stopped after 24hours but I’ve had this constant pressure/menstrual cramping and back pain since. I’m now 30 weeks today and have had various trips to LW and baby’s heartbeat strong and very active. They don’t seem at all concerned with how much pain I am in. I’m hardly sleeping for it and feel sick a lot. Each time I’ve been cervix has been closed but I’m so fed up. Please advise x
By Midwife @Tommys on 4 Apr 2018 - 10:36
Hi Kirsty. I am sorry to hear all that you have been going through. If you are in pain, then you need to go back into hospital to be reviewed on your hospital labour ward triage/day assessment unit.
The fetal fibronectin test is a safe, reliable, non-invasive test
(similar to a smear test) that measures the level of fetal
fibronectin in your vagina. This is done by performing a speculum
examination to try to visualise the cervix at the same time.
Negative test result means you are unlikely to deliver soon. If
you have symptoms you can be at least 99 per cent reassured
that you will not deliver in the next two weeks.
Positive test result means you may have your baby earlier than
expected. A small percentage of women who have the test
will get a positive result. This means that there is an increased
chance that your baby could arrive early.
The test results allow the doctors to make a plan of care for you
and your baby. This plan will be dependent on how many weeks
pregnant you are. The plan may include closer monitoring of the
pregnancy, changes to your daily activities. You may be offered
steroid injections to help mature your baby’s lungs should the
baby arrive early. You may be admitted to hospital.
It is important to note that not everyone with a positive test
result will deliver early.
What do I need to look out for after the test has been done?
Whether the test be negative or positive you will be asked to
contact your midwife or the hospital if you have any symptoms
of pre-term labour, which can include:
• regular painful contractions that don’t stop (eight in an hour)
• period type cramps that come and go or are constant
• changes in the amount, colour, consistency and smell of
• constant, dull back pain, loin pain or urinary cramp
• pelvic pressure.
Please do feel free to call us on 0800 0147800 if you want to discuss this urgently and in more detail. We are here for you if you need us.

Im currently 33 weeks pregnant and having a terrible 4th pregnncy. Last night for a few hours i had tightning cramps which lasted around 36secs per 1.5mins. I woke up feeling better but today i have had alot of pressure down below along with what i thought could be my plug. Im in alot of pain but dont want to call triage incase its nothing. Advice would be great.
By Midwife @Tommys on 26 Jan 2018 - 10:07
I am sorry to hear that you have having such a terrible pregnancy. You explained that the tightenings that you experienced are quite short and have now stopped which is reassuring, however if you are still in a lot of pain then as you describe then it is important that you call your maternity unit to be reviewed. This is particularly important if you have had any loss down below too. Monitor your baby's movements carefully too, if you notice any changes or the movements reduce then again please do call your maternity unit straight away.

My baby born 5 days back with 668grams(27weeks). Now baby is on ventilator. From last three days onwards giving mother feed to baby 1ml for every 3 hours. 1st day baby drunked perfectly. 2nd day baby drunked 1ml in 2hrs 30 min. 3rd baby taking 4hrs to drunk 1ml. Doctors told me like baby having some digestion problem. Could you please confirm me it is a common issue for all the premature babies. Meanwhile how many days baby will take to breaths on his own way.
By Midwife @Tommys on 30 Oct 2017 - 14:11
Hi. As midwives we do not have the expertise to advise you about feeding your very small baby. This is specialist care and would be best answered by the doctors and nurses caring for you. We hope that your baby will thrive and that you will recover well too. Best wishes to you both x
By Mrs Chantal Branton (not verified) on 20 Sep 2017 - 16:28
Hi I'm just wondering if you accept knitted items for the premature baby unit. Many thanks
By Midwife @Tommys on 20 Sep 2017 - 16:35
Hi Chantal, we at Tommy's so not have the facilities to be able to do so, although we would love to!
However, if you contact your local NICU, they will likely to be able to accept these from you for their poorly babies. They are always very welcome and delightfully received! Thank you so much for thinking of us, but they will be much more useful at your local hospital instead! Thank you for your support - we really appreciate it!!! Sophie, Tommy's Midwife
By Midwife @Tommys on 27 Jan 2017 - 09:41
The safest would be to avoid foreplay especially if anything was to be inserted into the vagina. Whilst the evidence is weak, orgasms and foreplay may possibly bring on contractions and released oxytocin (hormone) which can help to bring on labour. There are no definites I am afraid but the safest option is to avoid all forms of sex.
By Kelly (not verified) on 25 Jan 2017 - 16:39
I am currently 33 weeks pregnant and my waters broke at 30 weeks I have been advised to not have intercourse due to infection, does this include forplay? Sorry to ask personal question but I'm finding it so hard but at the same
Time don't want to start contracting or get an infection
