I know the feeling as well my DD is 2 1/2 and wants to do everything herself although she only ever says "I'll do it" and when we ask what "it" is she won't tell us and then will have a tantrum if we do the "it' she wanted to do.

I feel that by the end of the day my negotiation skills have waned and I just need to get things done, and with having the twins trying to be a bit more independent it makes it hard trying to dress/change nappies for 3 squiriming, wriggling kids. Luckily the boys haven't hit the full on demanding stage yet, I know what each scream, yell or cry from them means I'm hungry, I'm tired, I'm sick of my brother and sister
