I remember being like 10 or 11 and my mum still running baths for me! I can't remember if it was because she wouldn't let me do it or I wanted her to do it LOL.

My 7 year old doesn't run his own bath. I run his shower for him if he has a shower and he's been taught how to turn that off by himself. With the bath though, he has a 4 year old brother and I never know who is going to want a bath first so I just run it and then tell them to decide who's going first.

I guess the best way is too let them run their own bath but either supervise them or come in and check the temp before they get in it. My 7 year old has been known to sneak into the bath if I start running it then go to get their pyjamas or something and I come back in and he's in it. He got in trouble for doing that as he never checks the temp with his hand, he just gets in and I said to him "How did you know that wasn't just HOT water in there?" (It wasn't, we have mixer taps).
