22 Month - Not Sleeping at Night

Give her a cup of water to keep by her bed and that's it. You will probably have a few sleepless nights because she will really see how far she can push you, but don't give in. It's really not a good idea to take her downstairs with you to get it either...nighttime means you stay in your bedroom (unless using the potty) and you sleep because mommy and daddy need to sleep too. She will fight you really hard on this but if you're consistent and don't take her downstairs for milk and just leave her with the water cup, she will get the idea after a few nights.

My first recommendation is to ignore her/let her throw her fit, but you have said you are not willing to do this. So I think the next best thing would be to stop giving milk. I would recommend leaving a cup of water in there at night for her so that she can actually help herself to the water instead of relying on you. When she begins her fit, I guess I would go to her and show her where he water is that she can have a drink, but there's no more milk at night. Say it's bed time and place her back into bed. The less talking the better. Keep placing her back in bed. Don't make this a game for her by talking, making eye contact, etc. Keep putting her into bed and when she climbs out just place her back in without any reaction or emotion. This may be a VERY long night (or 2 or 3) for you and her, but if you keep at it and are completely consistent then she will begin to understand night time is for sleeping. It may seem easier at times to give in, but as you have said it can start to affect other areas of life and it's really not in her best interest either. Good luck, I hope it goes well.

Can you give her a sippy cup of water to keep near her bed (I assume she is not in a crib? Maybe I'm not understanding this.). Make sure she is really FULL when she goes to bed? Can she have a small bowl of cereal or something as her pre-tooth brushing/getting into bed routine? Is she thirsty? Is her room very dry?
Or do you think it's a power ploy?

Try putting her down 30 minutes earlier for her bed time. Sometimes when they are over tired they wake up at night and think they are hungry instead of tired.

my kids have always, since they were finally off a bottle and would drink from a cup, taken a cup of water to bed. I take a cup of water to bed, so I never understood why I shouldn't let them. it's worth a shot if nothing else, and water won't hurt her teeth. And from my experience it didn't change potty training either, my kids all trained early without issues at night even though they took water to bed.
