Premature birth - information and support

A 'premature' or 'preterm' baby is one that is born before 37 weeks. If your baby is born early they may need special care as they may not be fully developed.

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 [1]. The rate of preterm birth is between 7-8% across the UK [2].

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 [3]. 

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 [4].

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.

    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.

    Hi Caitlin,
    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.

    Hi,
    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.

    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

    Hi I'm just wondering if you accept knitted items for the premature baby unit. Many thanks
    Chantal

    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

    Hi,
    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.

    Hi
    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
