Just wondering really... my DD is nearly 3 and, although sensible in lots of ways, could not be left alone in the bath as I don't think she'd be safe. Was chatting to my SIL tonight and she said she'd left her DS2 (age 2) in the bath while she tidied DS1's room. Apparently he's very reliable and knows not to stand up etc. She is not far away and would not go downstairs etc.
I said nothing, but it seems very young to me. At what age did you consider yours safe to be left (while you still did the getting in and out, drying etc)?
