Wow, I could have written this post myself.

Although, my mother doesn't live with us - and lives half way round the world in Scotland.

Anyway, when they were here, our little miss was 4 weeks old and when she cried, mum would say that she was being a "bad" girl. When she was settled, she was a "good" girl. I soon put a stop to that telling her the obvious - she's a BABY! Her cognitive abilities are not yet developed, her brain is nowehere near mature enough to know what she's doing - and "well, mum, JUST SHUT UP!!"
The Science of Parenting is an amazing book and one in which I throw quotes at my mum all the time to shut her up - we still chat most days on skype and still she has stuff to say on my parenting technique. *Sigh*

It really bugs me when people say kids are being naughty. It's not the kid that is naughty, it's the behaviour and kids behave in negative ways for a reason - it's about finding out what that reason is. Trying to tell this to my mother, she sneers at me!!!!

I feel your pain hun, but you have to be firm with her. It will be better for you in the long run.
