I'm sat here in tears writing this and feel like a failure for admitting it.
Since my DD turned 5 her behaviour has been awful towards me. They tell me she is a delight at school and her grandparents say she is well behaved at their house.
However, she is just plain mean to me. She ruined my christmas by her constant tantrums and back chatting. Her most recent horrible comments have come regarding my weight calling me fat and comparing me to other mum's 
I just don't know how to deal with it. Tonight she called me fat and I lost it, shouted and screamed at her. Is this normal behaviour for a 5 year old?
