Outta the mouth of babes

So my 5 yo step son and I are at the store. He knows I'm going to have a baby, but isn't sure of it yet.. he tells me he's gunna be a big helper when it comes and help feed it with a bottle. So I ask him what he is going to do if it cries, he says he will rock it slowly. I ask him what if it keeps crying, he says he will sing to the baby. So I ask, what if it poops.... his response - lock it in the bathroom.... well if I can't find my baby its locked in the bathroom cuz it pooped...
