OK, so the first two times we tried to give Jack a proper bath he just screamed the place down. So we decided to just wash him with cotton wool for a while to get him used to being wet without being in a bath of water. We do this in front of the fire to keep him warm, we talk soothingly to him, explain what we are doing etc. But he still screams and "bath" time is a traumatic experience for all three of us. What can we try to get him used to being wet and get him into his baby bath?
