Movement?!?

Abby

This baby is stressing me out. I'm 30 weeks now, and since he started moving, he always is either moving a ton or is completely still. I'll pass a few kick counts a day and take less than half an hour every time, but then take huge 4 or 5 hour breaks where I don't feel much of anything! Already been in for an NST and ultrasound and everything is perfect, but I can't help but worry constantly. Anybody else have a baby like this??
