What Age did you let your toddler bath alone???

Rarely - DD#1 is 4 and DD #2 is 1. Ive gone to check on the pasta for dinner, come back and both the little devils have splashed water out of the bath onto my bathroom floor - more water was out than in. Not happy. :(

DD is 3 and I leave her in there while I'm dressing DS. I'm only a few feet a way and I can hear her talking, splashing etc and I call out to her every minute or so and she knows to answer me.

My eldest was over 4 before i left him alone. I did sometimes run to get the phone or towels ect but i would call out to him.. My second son was around 2 as the boys bathed together and I was just pottering around fixing up their rooms for the night which are on either side of the bthroom anyways..

now all 3 or just my 2 youngest boys bath together. We can hear them at al times..

i used a bath seat for Krystal up untill we moved house in November (she was 17months) she was very loud so i could duck out to grab a face washer or something, but id never leave her for more than a minute.

now she showers with me everyday... we havent used the bath in this house! she seems to love the shower, she has foam shapes that she plays with so she is happy to stay in there as long as i am!

If DD is in the shower i will pop in and out, as i put her heating on and get her PJ's out and such while she's playing with her toys on the bottom. Oftentimes she has a shower when i do. In the bath i will duck out for a towel (the laundry cupboard door is at 90 degrees to the bathroom door, with the edges almost touching) but don't go into other rooms or leave her for more than a few seconds. She's 22 months.
