I am just over 21 weeks and started feeling my first movements at around 16 weeks. With my son, he was wriggling, kicking and moving all the time but this time my little girl hardly moves at all. I might get 1 or 2 movements out of her a day, some days more, some days I don't feel a thing. Also it is softer movements, subtle, I really have to concentrate to feel them but with my boy at this stage they were much more intense. Is this normal? My placenta is same as with my boy, out of the way so what's different?
