How big is my baby at 20 weeks?
By week 20, your baby will now measure around 16.5cm long, head to rump and around 25cm from head to heel. They are around the size of a banana and growing quickly!
If space allows, they are still having fun turning somersaults, and perhaps still taking you by surprise as they do so.
Although they are mainly just growing bigger and stronger now, there are some key elements of their development going on as the nerves in their brain which control the senses are still forming, eventually enabling them to smell, see, hear, taste and touch.
They will also start producing Meconium in their bowel. This is a harmless mixture of amniotic fluid that your baby has swallowed, digestive secretion and dead skin cells that will form your baby’s first bowel movement after birth.
Facts to know about your baby in week 20
- By now your baby can hear your heartbeat and outside noises like music
- Your baby's hair is starting to grow
- Your baby is now formed and turning somersaults
- From 20 weeks onwards babies are measured from the top of the head to the heel

You might experience some aching in your tummy as your bump continues to grow – this is due to the ligaments each side of your womb stretching as your baby gets bigger and bigger. It is perfectly normal, but as with everything, do mention it to your midwife if you are worried.
Some women develop pains in their pelvis called pregnancy-related pelvic girdle pain (PRGP) or symphysis pubis dysfunction (SPD) when pregnant (again, not dangerous, just uncomfortable) which can be treated with physio or support girdles.
Your bump might mean you are struggling to get comfy in bed at this stage too, and so you could be feeling tired because of interrupted sleep. You can buy specially shaped pregnancy pillows to help support your bump and enable you to get a good night's rest (many of these are also useful post-pregnancy for breastfeeding), or simply to offer you more support when you are sitting or chilling on the sofa.
Facts to know about you in week 20
- Pregnant women have less oxygen in their blood, which may explain 'baby brain,' or forgetfulness
- Drink cranberry juice to help prevent urinary tract infections (UTIs)
- Pregnancy is the only time in life when you'll fall in love with someone you haven't met
What to think about in week 20
If you have pets you might be wondering how to best introduce them to your new baby when the time comes, or how to successfully designate certain areas of the house pet free! Of course, your animals should never be left alone with your baby, or have access to their pram or cot, but you can take steps to additionally protect your little one from inquisitive pets.
Nets that go over your Moses basket or cot are easily available on the high street, and baby gates have a plethora of uses which are not just restricted to keeping toddlers away from stairs!
Chat with your vet for professional advice on prepping your dog or cat for your new arrival – although as long as basic common sense and safety is applied, you should all manage just fine!
Now you’re at the half way point in your pregnancy, thought of your maternity leave may start to creep closer and closer. But have you actually worked out the best time to start your maternity leave? Have you had the conversation with your employer? Now maybe the time to tie up all those loose ends and making sure you know what you need to know and get sorted.
It’s not an easy decision figuring out when to start your maternity leave. The decision can be made more difficult if you’re experiencing severe pregnancy symptoms or work in a physically demanding job, so continuing in your job towards the end of your pregnancy may feel unrealistic but you want to want to ensure you get to spend as much time as possible with the baby after it’s born.
To help you with your decision we’ve got the headline facts, alongside some advice on what to think about when choosing your leave date.
At this halfway point of your pregnancy, you may also be starting to think about signing up to antenatal classes. Wanting to understand what they are all about, how they can benefit you and what classes are available in your local area can seem a bit baffling, but antenatal classes can benefit you in many ways.
They aren't simply to teach you about breathing exercises and learning how to look after your baby once you arrive home – they are also a great opportunity to make the basics of how to make friends with other mums going through exactly the same mum-to-be (and then new mum) hurdles as you, and more importantly, at the exact same time you are facing them.
