I feel like a bad mommy..

The baby's favorite spot to lay is somewhere on my stomach/liver. And when he does most times that causes like a sharp stabbing pain. The bigger he gets the more it hurts. My doctor showed me how to get him to move off of it at least for a little bit.( thank God for some relief) but it was so bad last night that it woke me up from a sound sleep( which I hardly ever get) multiple times. I'm so worn out today that every time he moves it kind of frustrates me. I kind of just wish he would stay still for a little bit. But then that makes me feel horrible what kind of Mommy get slightly frustrated when their baby moves? I'm guessing I'm just really sleeping and this pain is starting to really bother me.??
