I am losing it with my kids. tonight i dragged ds up the stairs and put him in his room. in my blind anger i didn't realise he had bumped his head on the bannister on the way up and now he has a bruise 
it is just the usual. pre xmas stress, rudeness,cheekiness etc. no excuse but i am exhausted this yr. now i feel like the worst mother in the world for basically abusing my ds
