Hi wobbles, it all sounds completely normal to me, and was nothing you did or didn't do, so don't worry
I have two sons and 1 daughter, and fair play to you having two daugthers, they are truely a special case compared to sons!
I.f it makes you feel any better , my one is now 8 and doesn't go a day without screemign the house down , in public or yes still dropping to the floor in a supermarket(just does it with more style).
We have to deal with her with a zero tolerance type attitude or she is soo bolshy she would walk all over us and get even worse, so does this zero tolerance get us anywhere..... NO but nor does it get her anywhere. She will not be ground down, she will sit on that naughty step (yes at age 8) and she will sit there, and sit there, will she apologise? .....NO, thats not in her nature.
But do you know thijs last year I have realised that under there this is a sweet girl, that actually has low confidence and self esteem, and is dying to be loved all the time, so there must be something in that that's casuing this behavior.
Anyway, I will stop rambling about me, just wanted to show you, you are sooo not alone, and girls are a nightmare, you have two!
I would say , try to ignore the bad behavior, using the naughty step to exclude, but leave it at that, then reward even the smallest of good behaviors a one will lead to another once you have started.
as free prizes - try to give more control to her life,even at age 2. if she is good at breakfast - offer two choices of clothes that you have chozen, that way you win and she thinks wow I'm a big girl and yet you still have control really. Offer two time with mum activites, playdough, painting etc , get her cleaning with you when little ones asleep, she will love it, Briony loves to help me and feel big and useful.
just an idea from a mum who is still trying to find the right way to deal with her handfull, it's just finding a way that works for you and caitlyn
Perhaps she will not need to asert herself in such extreme ways if she feels more in control, just an idea - oh and mine will actually jump through hoops for a star chart!!! I think it was tesco or Smiths do a lovely magnetic one that can hang on the fridge, with spac to choose your own reward.
