Hi my DD has started smacking other children and myself, I keep telling her no and if she smacks me whislt I am holding her I insantly put her down. My sister and I share childcare so I am watching my Nephew today (20mo) and she keeps making him cry because of her smacking, I have moved her away from him, told her to give him a cuddle to say sorry but she just won't stop. Is she too young for a naughty step? Really need some advice as I am getting frustrated that she won't stop smacking.
