Your baby dosent have to move that much.
Are you laying down while feeling for movements and counting every kick, roll, and flutter you feel?
Every baby is different i would sugest jeping a movments diary for a week and see if you can figuer out his patten then id only worry if there is a suden decress in his movments. But in saying that I'm not a dr and if you are worried maybe you should get a second opinion
Like when im sittting down he loves to kick on my right side, or at night but he doesnt move like crazy i can say his a calm baby!
I do count his kik he wont kik more then like 6times a day!! And he only likes to kik when im sitting down!
