Kia: I prod at baby for my own entertainment too. I figure I'm growing him, I can poke him if I want My DH made me ask my doc when I was pregnant with my first if I was hurting her and his answer was basically I'm going to hurt myself long before I hurt the baby with how much cushion they have.
LOL, you might not hurt him but you might make him neurotic. :P Just teasing!
I read the other day that baby can now feel hot and cold so the peas would probably work. I haven't had much rib troubles yet, thankfully!
