Thanks girls, put him in the shower with me as I thought he probably wouldn't sit down in the bath. He still cried the whole time poor thing.

It's completely covering where the nappy was, even on his testicles, does it sound like radiating? This was HOURS ago, can't believe it's still so bad! I now have an almost full packet of pull ups to give away.

At the moment he's ok with a nappy on very loose to catch the pee but don't know what I'll do when he wants to go to bed.
