It's common, Mommy. It's the best feeling ever. I'm sure your baby just wants to play with you, or maybe telling you that your little one is excited to see you. Just caress your baby bump, talk to your little one, you may read story books to keep your child company, bond with your baby while she/he is inside of you because once your baby is out, you're surely going to miss it.
