My DTs (identical girls, 30 months) love playing in and with water in any shape or form. Until recently bathtime has been great; we put them both in the bath together and with plenty of splashing we usually get them washed (and ourselves soaked) without too much trouble.
Just recently they've started getting hysterical in the bath - you'd think it contained boiling oil for the reaction they have. One of them kicks off, screaming and crying, "Want to get out" and grabbing us, which naturally sets the other one off and we end up with a very quick and fairly stressful wash followed by lots of calming talk and cuddles to restore everyone's equilibrium.
I'm not aware of any incidents (hot water, falls, etc) that might have put them off baths, I was just wondering if anyone has a similar experience or any suggestions.
We haven't tried bathing them separately, though this is the next thing to try I think. Showers are out - there is a shower over the bath but turning it on just results in the girls fighting to get up the other end of the bath and as far away from it as possible.
