Watching your child develop can be one of the most fascinating aspects of parenthood. As your baby's brain and body grow and their pathways gradually connect up, babies learn to smile, then crawl, walk, speak - and develop many other skills along the way. If you're concerned that your baby may have health problems, the excitement you feel as you watch them develop may be mixed with worry.
Factors influencing your child's development
Premature birth can affect the way your child develops, and the earlier your child was born, the higher the risks, so you need to keep an eye out for any area where you think there could be a delay. However, it's all about striking a balance: every child develops in their own unique way.
Your baby's development will depend on a range of factors, including:
- genetic make-up
- the environment
- influences around him.
Development milestones are based on averages. Not meeting given milestones is not just an issue for pre-term babies. Term babies sometimes do not meet development milestones either.
How their time in hospital can affect premature babies
There can be some delays in the development of motor skills among premature babies, partly due to treatments when they are small, such as being on a ventilator, although growing awareness of positioning techniques is helping to reduce this.
If a baby's experiences in the unit prevents them from developing appropriate muscle tone, this can have a knock-on effect. For example, if they achieve sitting later than expected, this in turn can delay subsequent skills, such as hand function.
Delays appear to be becoming less common among babies with a birthweight of 1 to 1.5kg.
Prematurity and growth
Premature babies start small, and although they do tend to catch up as they get older, children born very prematurely still tend to be smaller and lighter than their classmates. However, as our knowledge of nutrition continues to develop, and with extra supplements available to support premature babies' dietary needs, this may change.
As premature babies develop through childhood and adulthood, it becomes harder to know which of their traits and characteristics are a result of premature birth rather than other factors.
As your child was born prematurely, they will be considered in a high risk group for developmental problems and they are likely to have more assessments of their progress than a term baby would. This is routine, not because there is something wrong or there will be something wrong but because early detection and diagnosis of any potential problems are key to prevention.
Many low-birthweight babies and their families are invited to attend follow-up or neurodevelopmental clinics so that the healthcare team can assess the baby's progress and intervene early where treatment is needed.
Where possible specialty services will be co-ordinated so that you do not have to attend many appointments. Follow-up visits will also be scheduled during the first years of their life.
As well as looking at how your baby is developing, the healthcare team will regularly check their weight, head circumference and height (also known as length) to make sure they is growing as expected.
Understanding your baby's growth chart
You will be given a Personal Child Health Record, or 'red book', which has growth charts to help plot your baby's growth and compare it with the average growth for their age. Babies born at less than 32 weeks are plotted in the low-birthweight chart. Babies born at 32-37 weeks are plotted in the preterm chart until two weeks after their estimated due date and from then on are plotted in the main charts, but with their gestationally corrected age.
How centile charts work
Babies' progress is described in measurements that are called centiles because they relate to average percentages. The curves on the chart show the usual progression for a baby, as a baby's weight will normally increase and level off at certain ages. So, for example, if your baby's height is in the fifth centile for their age, that means that if you lined up 100 children in order of height, your child would be at number five, with a child at the 100th centile being the tallest. There are separate charts for girls and boys, as boys tend to be heavier.
The centiles for weight and height should usually be similar - if they are very different from each other, this may indicate that your baby is overweight or underweight, and your team may need to adjust the feeding regime.
Rather than 'targets' to be measured, it's more helpful to view milestones as signals that some premature babies might need extra help. Throughout your child's early life, the healthcare team will observe their development and measure their progress against milestones.
These are usually carefully worked out targets based on the average age at which children tend to develop certain skills. For example, 8-18 months is the average age when a child will start trying to walk on their own. The milestones have been designed to help professionals spot problems early. Remember that term babies may not meet development milestones either.
Early babies are given time to catch up
If your baby is born prematurely, their milestones will be assessed from the time of their due date, not from when they were actually born. By the age of two, their development will often even out with their peers, and you can use their actual birth date instead. In very premature babies, sometimes this is extended to three years of age.
Making progress, step by step
Going back to our example of the walking milestone, if your child doesn't start walking at 10-18 months, this does not necessarily indicate a problem, and your child may well catch up later on. The healthcare team will flag it up anyway, and may refer you to a specialist, as in some cases it could be a sign that they could need some treatment or therapy to support their development.
Using milestones to your advantage
You can use milestones to your advantage in three ways:
- To encourage your baby's development. For example, if you know that babies can start to roll over from about two months of age, you might notice them trying to flip themselves over and you can give them a helping hand
- To keep your baby safe. You will be less likely to leave your baby lying on a sofa if you know there is a chance they could roll and fall off
- To spot whether your little one could be falling behind. If there may be a problem in a particular area, you can seek advice more quickly.
Try to avoid comparing your child to others
It's easy to become very focused on comparing your child with other children. Some parents find themselves thinking of milestones as 'targets' that indicate the success or failure of their child. Instead, try to see them as signals that can open doors for you if help is needed. Missing a milestone doesn't necessarily mean that there's any kind of problem.

Hi my son was born at 23+6w weighed 1lb 3oz
Today he is 24+6 weeks actual (8+5 adjusted) apart from chronic lung disease you wouldn't know he was a Prem baby
He's started to smile, coo and started to get the Attachment phase, he's become very clingy and separation anxiety is this normal for this early on, I was told this shouldnt happen yet. Does that mean my son is advanced for now :)

Hi and congratulations on your success. How lovely that he is doing so well. The first few smiles are so special but perhaps especially for those babies that had such difficult beginnings.

Hi my premature baby is 5 months now and struggling with posture and sitting on his own, he was born at 35 weeks weighing 1,7kg. should I be worried?
By Midwife @Tommys on 9 Feb 2017 - 12:06
Hi, Most term babies are sitting up by 6 months but some still need support with cushions, so it is still early for your baby. If you are concerned about his development though, please contact your health visitor. If you haven't seen her/him recently you can find contact details in your red book.

Hello and Congratulations on your twins!
Every baby develops differently and each reach milestones in their own time. It sounds like your babies are doing well and seem active and interested in things around them. However if you are concerned, I would advise you to speak to your health visitor for support with this, who can advise on what to expect and provide essential support and advice.

My baby was born at 28+1 weighed 1.35kg. Now 11+5 weeks. He does cry though little. He tends to "grunt". He does tend to sleep more than a newborn at term, we're not quite at his EDD. Is his behaviour normal or known with preemies?

Hi, your baby should be getting weighed regularly (at least monthly) and this should be being plotted on his growth chart in his red book. Ideally a baby should followed along the centile they were born at however this can vary a little. If his growth is dropping a centile or more then the health professional should talk to you about the feeding and his well being to see if there is any further support needed. If you have not had him weighed for a while then you can access baby weigh in clinics in your area or speak with your health visitor about you concerns. Tommy's Midwives x

Hi, my daughter was born at 30 weeks and weighed 1.1kg. She is now one and has recently had her 1 year development check however they done a 10 month check to allow her some extra time. She was in the 'black area' for everything and has had to be referred to specialists. She has had many complications at birth and since and I'm concerned, is there any advice you could give?
Thank you in advance.
By Midwife @Tommys on 18 Nov 2016 - 09:21
Hi, I would advise you to speak to your health visitor for support with this. The development check is a screening tool and not diagnostic so it is difficult to say if there is a problem or not without a further referral. When she had her review they can provide you with activities to do with your daughter to encourage her development.
By Midwife @Tommys on 9 Nov 2016 - 10:02
You should discuss this with your Health Visitor as your baby is now over 6 weeks old . It may be that you should try a different milk and see if that helps but you will need to discuss this with your Health Visitor. Try not to be too concerned

By Midwife @Tommys on 17 Oct 2016 - 09:19
I would suggest that you ask your health visitor or Gp about your son's growth and go from there. Try not to worry at this stage.

My premmie was born at 33weeks n 5 days. She is 6months old now,very active,healthy with no complaints. She has not started sitting up but she can sit with support. When can she start sitting up
By Midwife @Tommys on 5 Oct 2016 - 16:02
Hi, it is great news to hear that your daughter is doing so well. In regards to her development I think it would be good to make an appointment to discuss her developmental milestones with your Health Visitor who will look at this in context with her premature arrival too.

My baby who was born at 35 weeks started to sit at 10 months and started to walk at 18 months my doctor said it is normal for premature babies to catch up late
By Midwife @Tommys on 17 Oct 2016 - 09:20
Speak to your health visitor, he or she will be able to discuss your daughters progress and development in more detail with you, knowing your child's history.
