or just mine?! They are 2.5 and 3.10 and generally completely ignore me when I tell them to stop doing something. DD (oldest child) is worse - it is generally over something stupid, like I will tell her off for putting a coin in her mouth, and she will do it again straight away. It drives me mad! I would be quite strict and always follow through i.e. I never just ignore it when she is disobedient (though maybe I should!)but I take it this behaviour is normal?
