Psy, I'm glad you said about the squirming rather than kicking because I've really noticed him moving more than kicking recently and I wasn't sure if that was normal so I'm glad it is.
Natalie, I often feel him move on both sides of my tummy at the same time so I always wonder if he is lying accross my tummy. Other times I can feel movement right up inbetween my ribs. Sometimes he presses or moves against my bladder which can be a little uncomfortable. I get some really strange movements sometimes and wonder what he is up to in there, I wish I could see what he is doing.
