My baby is moving but....

Sj`s Mommy
So I had my OB Return appointment the other day (2 days ago) and he told me to sit down once a day and make sure I felt my baby 10 times within an hour. I do feel her 10 times, but her movements are much smaller than they used to be. It used to feel like she was doing flips inside of me and she used to kick harder at times. Now all I feel is mostly really small kicks. Should I be worried? I am happy that she's moving but I just want to make sure I'm doing everything right!
