Hi A., I don't think the issue should be so much that she has to go back to sleep, the issue should be more that she needs to stay in her bed unless she has to go potty, you go potty then you go back to bed, you can't force a child to fall a sleep, but you can inforce them staying in their bed. If you been going into her room for 3 months, or even 3 weeks, and lye down with her, or sit on her bed, you created a habit, so now her waking up is like clock work, so now you need to reverse that, how do you do that? well when she wakes up tonight, don't go in her room, I know that, that might sound mean to you but it's not, she needs to learn that no one is coming in her room 2:30 or 3:00 in the morning, if you plan on ever getting a full night sleep, your have to reverse this thing, because right now, she controls the amount of sleep you get. We had a simular problem when my first born
a son and my husband nip it in the bud right away, it took discipline, that a mom plasted me for, but children need discipline, structure and they need boundries, with out them, they are in charge. If you want I will share more with you, just let me know, but get your rest A., becasue rested you will be a better mommy and wife, not that you are not a goon one now, you'll just be better with rest.
