10 kicks in two hours. But if you don't get that the first try, try again in an hour before calling the dr (unless you've had something happen prior like a fall or something) because babies sleep a lot in the womb (:

my baby is very active, so I feel way more than 10 movements in an hour!

I have heard 10 movements an hour. But just read the other day that it is not accurate anymore. You are supposed to snack and lay back and track how long it takes to feel 10. Should stay in the same range - according to that. My doc said there is no set amount. As long as there is movement :)
