Forty weeks, the baby is very active, spinning around and round ? He/She sleeps only when I want to lie down, then everything starts! When I stand still, he/she pinches me until it hurts, even in some places. It's painful. Mommies who have been there, how much does your baby weigh before the birth? Maybe this is a sign that he/she is going to come out soon ?
