Just simply a bad habit hon... My husband and i made the same mistake and i went to my parents and they said you have to let them cry it out.Night after night and down the road it will work.Its just heart breaking thru that time till you get there.But put her in bed make her feel comfortable as possible and maybe a night light then leave her if she gets out of bed you put her back and you keep doing it.Yes it might be a few long nights. But after i believe it was 4 or 5 nights it finally worked for us and we kept telling what a big boy he was and we tried to give him special blankets and animals to help also. We would also say if his favorite animal didn't get to sleep in his bed he would be upset. But not matter what its time engery and crying. But it will work you just CANT GIVE IN!!!!!!!.Thats the hardest part but from my own life trail. When you want a child to do something you have to stick to the pattern,AND NOT GIVEN IN...hate to say this but its just like training a dog to pee outside. You just have to keep working at it. Good luck!!! AND DON'T GIVE UP AND DON'T GIVE IN!!!!!
Mom of a 22 and 20 old boys... p.s i still have to stick to my guns even at this age that something you will always have to do , Put that foot down and keep it there or they will get what they want and not what you want. BEST OF LUCK
