My DD is like that now, and always has been. She's very reserved and quiet. On the positive side, at 2 weeks shy of 2, she knows all of her body parts, even things like knees, shoulders, chin, and forehead. She's also learning her colors and starting to pick up letter recognition. Laughter is good, but it's no biggie If they aren't as jovial as other munchkins, it just means they're busy learning.
