There are several ways in which your baby can now move: he can curl and stretch his trunk, move his head up and down and from side to side, and move his arms and legs independently. Regular chest wall breathing movements occur, along with occasional hiccups. The mouth can open and shut, and your baby can yawn and swallow amniotic fluid. He'll bring his hands up to the face and prefer lying on his side rather than back. He has plenty of space in which to move.
Your baby's taste buds first appeared at 10 weeks and by now have an appearance very close to that of a mature taste bud. They also have their own nerve supply, connected to a branch of the facial nerve. Because these neural connections have not yet matured, it is too early for your baby to be able to taste anything.
