Anyone else's baby like to hide?

Annie

I'm 21 weeks and my son is rarely near my belly button but instead favors laying balled up against my bladder really low. Every sonogram he's curled up near my cervix. I can feel him wiggle every once and awhile but only a few times has he come up higher and kicked around and my husband still hasn't had the chance to feel him. Anyone else's baby like to hide?
