Yu can always do kick counts to monitor if everything is okay..that's what my doctor told me to do. Yu drink some cold water and lay down then yur baby should move at least ten times within the hour..
Yes! Around 21/22 weeks my baby had a lot of lazy days, it's completely normal though; they are sleeping more than half the day at that point anyways :) I'm almost 27 weeks and she still has lazy days.
