Hi Deb - Keep your chin up your not a failure just a stressed out mum, I know I have two girls who argue constantly. Do you shout at your little girl when she plays up because apparently they just shout back, also regarding the problem getting her to go to school, remind her of how much fun school is and how she'll get to see all her friends, and perhaps ask her to paint ' Mummy a pretty picture ' also try to get more involved with her after school, let her help you with the dinner ( even just putting things in the saucepan )or let her help you with the housework give her an old duster and ask her to be mummys' little helper, or let her stand on a stool and wash the dishes, you'll probably have to wash them after but at least she'll be quiet, also get your partner involved in this and bathtimes and bedtimes stories,
Just an Idea
Best of Luck
Joanne
