At 16 weeks pregnant your baby is now around 15cm long and has tiny little fingernails and toenails at the end of their growing hands and feet. Although it may be still too early to feel your baby inside you, they can now turn their head and exercise all 40 sets of muscles. Although their eyelids are still closed, they can sense light from outside their cosy little world. Your baby now has tastebuds and is starting to make different facial expressions as facial muscles develop and eyebrows form – all of which makes them look more baby-like. Your baby is busy inhaling and exhaling amniotic fluid which helps their lungs develop. Their legs are growing longer than their arms and, in anticipation for all those kicks later in your pregnancy, your baby can move all of their joints!
