My 3 year old daughter will not say please and thank you to us at all - she has gone on strike from saying it and it has become a power struggle now. We have decided to not give her any treats (biscuit, icecream etc...) without saying it but she just says 'I don't want one then' and would rather not have it than say the 'magic words'. Sometimes she comes across really ignorant and I'm embarrassed in front of other mum's.
I'm not sure what approach to take now?
She isn't rude, she does say 'can I have....?' she just doesn't want to give in and say the words!
