My baby keeps a hand up by his face and just as I was typing that, he goosed me! He moves his hand around and it makes me jump. The other day, he was moving his hands around like he was washing his hair and it was very uncomfortable on my cervix. It's just one of those sweet little discomforts of pregnancy. I just hope that he moves that hand before labor begins.
On a side note, I was performing a ve on a client in November and her baby's hand was on top of her head. She moved it after I touched it, but it is an amazing feeling to feel those little fingers through an intact bag.
