I was touching LO's head today and it feels like it's a little knobby on one side. I know that it takes up to year for their skulls to be completely fused....but I'm a worrywart. Have you had an experience with knobby heads? Or even heads that are flatter on one side than the other? (I've been religiously turning her head from side to side when she naps so it's nicely shaped, LOL). I think I'm just paranoid because LO was a preemie so anything that doesn't seem "normal" I think is related to her prematurity...if that makes sense...
