This is how every bath (and everything else) starts....time varies on how long it lasts. For bath it is getting better. At this point, his diaper hasn't been taken off and he is standing outside of the bathtub here.
5-7 minutes of that above screaming and then you get this.....
Maybe even some happy playtime between them during the bath!
And when its over, success....two clean kiddos and a handsome Oscar!!!
