Your baby is now around 11.6cm long, with fully formed arms, legs and joints. Greater mobility in the hands can be seen, and your baby will now be able to suck its thumb.
Your baby will also be able to make facial expressions although they won’t be able to control this yet.
Your baby can be active for up to five minutes at one time now and you may start to feel some slight movement. As the placenta acts as a cushion, it absorbs some of your baby’s strongest movements and so women whose placenta lies closer to the back are likely to feel their baby move at an earlier stage than women whose placenta lies on the front wall of the uterus. So don’t panic if you haven’t felt your baby’s flutters just yet.
As a 16 week pregnant mum to be, your breasts may continue to get larger and more tender and you may find they have already started making colostrum – a special kind of milk packed with nutrients to sustain your baby in the early days.
You may be thinking about tests and scans and may be feeling better as the placenta has taken over the job of nourishing your baby.
If you’re getting the midnight munchies as part of the 16 weeks pregnant symptoms, try having some snacks that are packed with nutrition to help stave off those hunger pangs. Cheese, eggs and milk are just some of the foods that are high in amino acids and this should stop your tummy rumbling.
