Oooohh, the bloody trials!
It's a recent thing; he's done it before. But he's just decided that bath time is for losers. He screams from the second he goes in, until the second he's plucked out. I've tried not bathing him for a few nights; no difference. He had a poo explosion tonight so it had to be the bath. He almost screamed himself sick.
Sigh. He's 14mo btw.
