Get in touch with your local sure start centre and HV, tell them what you behave said here, and plead for support!
Priase her, for every little thing, make it specific, make it glowing, vary it-
" wow you are walking so well to school, I am so proud of you, what lovely walking, wait till Mrs ...sees you" and so on. "you've got your top on now, thats brilliant we are almost finished getting ready now, then you can have your coco pops which you love. Aren't you working hard, aren't you good?" Do it for EVERYTHING
Get a meeting with your childs key worker, and the play leader. Get them to advise you on what they do at nursery and what you should do at home. Get on the same page as them and do the same things. Ask to set up a home link book in which something positive from home is shared and read out to everyone and your DD gets a sticker. Get nursery to do the same and make a fuss when she comes home. Take pictures, write "wow" moments down. Encourage her to see the joy she can create and brings. Make a happiness scrap book.
Set your rules and stick to them. It might take a while to change, but consistency is key. I would say at least 3 weeks of being completely to the letter you might start to see change.
Can you put 2 stair gates across her bedroom door and secure her in her bedroom? Make sure this is safe and she won't pull them on herself.
Choose new bedding and PJs at the weekend and start building up to a new bedtime routine. Talk it up. Bed by 7-30. Bath at 6-30, then stories, then cuddles and songs, then bed. Keep physically putting her back to bed. Keep doing it and doing it and doing it. Get a mate round for moral support. Keep doing it.
If she is throwing things around, remove them. Lock everything away that is a risk and they can come out when she has come round to the new way of things.
I cannot stress this enough, but be consistent, pile on the love and happiness. Try not to get stuck in a negative cycle.
Give her a sticker chart with jobs on it that she can do everyday. Make some of them serious (put shoes away, take your cup and plate into the kitchen after eating) and some silly/happy ones (give mummy 3 kisses, clap your hands and touch your toes 4 times) little stick drawings can help make these lists accessible.
try saying yes rather than no. Stay calm, do not lose your temper. "Yes you can play on the tablet, after you have eaten your supper" "I think thats a bad idea because..."
If you feel like there is something underlaying this behaviour...talk to your GP.
Good luck, and HUGS!
