I'm very strict about stairs and baths. Breaking necks and drowning worry me. DH is ovens and fires 
Anyway, I'm dozing this morning, DH and DD (3.0yrs) are in the bath. She won't let him wash her hair so he comes in to ask me to do it. I went mad and told him to get back in the bathroom this minute etc. He looked at me like I was mad and said he thought that was while she was a baby/toddler. How much longer were we going to sit watching her in the bath? He was good natured about this btw not having a moan, just surprised.
So who is right? Is 3 old enough to be left for as long as it takes to get a towel/pyjamas whatever?
