I have found DD does the same, and there's no distracting her!! Now that she is starting to walk, she's trying to walk in the bath without holding on. I draw the line there, LOL. If she insists on doing it, it's byebye bath. Standing isn't such a worry for me now, we have the non slip mats in the bath so it is less likely she'll slip over, though she has and has just come up spluttering. She is yet to really hurt herself *knock on wood!!* she just gets a bit of a scare sometimes, but she's learnt to deal with it. I would say just stay next to him because you will both just get really frustrated if you try to stop him, and that might cause him to dislike bath time.
