We are so exhausted with it. We put her to bed and she (dd6) will demand a drink/snack/toy/phone and scream for hours refusing to go to bed until she gets what she wants.
Of course we try not to give in but she won't stop and there gets a point where we can't take any more and give in so when we try and be stronger the next time she just fights for longer.
It's every night and bedtime is just an example, tonight she had spaghetti bolognaise and wanted cheese on top she got that and ate the cheese first and screamed and refused to eat anymore without more cheese.
If we give a consequence she'll scream and scream about it and as much as we know giving in is the problem, it's become so much of a problem that it takes over the whole evening and nighttime until we are so exhausted with her we just have to give in because we have no energy left and need to go to bed.
I know we've done this ourselves but I don't know to change it now it's done.
