The washer on the tummy works wonders. Ashley will get used to it as she gets older, my DS was a screamer too until a month ago. He's just scared of being naked, makes him feel vulnerable I think. So the washer on his tummy made him feel like he has clothes on. We just did it really quickly until he became used to it so it wasn't a trauma and he didn't associate it with a negative thing. Now that he actually likes it, I make it much longer.

I also have a bath with him sometimes and he loves it, just the temp I have to bathe him in, I find really cold for me (i feel the cold badly)
