Oh God yes, my little man squirms so much and feels like he's pushing his bum into my ribs, or his fists/elbows into my hips - it's really painful! It's like he's trying to see how far he can push my skin!
It does make me laugh though because I feel really sore on the inside, and when he starts I'm like, please bubs give me a bit of rest (he's ridiculously active)... then he has a quiet hour and I panic and want him to beat me up again!
