Developments for 31 Weeks - Monday 5th March 2007

Your baby
Your baby weighs about 1.6kg (3.5lb). His crown to rump length is 28cm (11.2in) and his total length is 40cm (18in).
What’s happening
From now until heis born, your baby will gain weight faster than he increases in length: he’s laying down fat, which makes his skin look plumper and healthier. His digestive system is getting ready to process milk; the rest of his organs are continuing to mature. He’s putting his developing lungs to the test by inhaling and exhaling amniotic fluid more and more frequently in preparation for the day when she will breathe air.
Sweet tooth
Your baby already knows what he likes to eat: studies show that if a sweet liquid is injected into the amniotic fluid, he will swallow more of it!
