She needs to learn how to self soothe.
When you put her to bed, remind her that you will not be fixing her blanket in the middle of the night. That she is a big girl who can absolutely do that for herself. Make sure she has a cup of water in her bed - we always left a sippy for them in case they got thirsty. If she wakes up and calls, go in, but don't fix anything. Tell her that she's a big girl and that she can do that herself. DO NOT get her juice. That's a nasty habit. If she asks for juice, remind her that her water is there.
Walk out.
If she screams, let her. Simply walk away. She wants attention and if you don't give it, she will stop.
It won't fix itself immediately, but it will eventually fix itself.
You need to be firm. You need to be consistent.
If you give in once and fix her blanket or try to soothe her, it's all over.
Think about it this way: If she threw a tantrum like this during the day, how would you react? What would you do? You'd walk away and ignore her... right? What's the difference??
