Hi A.- I, too, think maybe the schedule is a little late, but the simple answer to your question of "how can I get my daughter to sleep sooner" is, You can't. At 2-3 they usually do a "I'm not going to sleep" thing. It is independence and wanting to have control over their world, coupled with transition to not needing a nap. I agree that she is too young to skip a nap entirely. You will want to work on her schedule for school. She will be eating around 12, naping around 12:30-3:30, snack around 3-4, depending on the school. So if you don't get her on a schedule closer to school schedule, it will be a harder transition for her to start school because her entire routine will be upset. You're in a tough spot, because it sounds like you're a family oriented person so I'm sure you want to have meals together. I think you will have to make a choice. Either scale back her hours and she eats alone, or scale back the hours for the family and everyone eats earlier. Even at that, we eat at 6 and some nights my 3 year old refuses to go to sleep and stays awake until 10. The general rule is, you cant force them to sleep so if they want to stay awake they need to do so in their bed, lights out, quietly. Even though she actually poops, don't kid yourself. She knows exactly what she is doing and is manipulating the situation to stay up. You must let her use the potty, however. But it should be an immediate poop, and straight back to bed. No reading a book on the potty or playing. As far as TV goes, I dont know. There are people (Drs. and the like) that say TV is too stimulating for that age before bed. I have tried to cut it down, but more for making him engage in other activities. He has a choice of TV three nights a week. The other nights are either reading, preschool activity books or family game time (board games, etc.) I dont really find any difference in the way he goes to sleep or the way his sleep is when he doesnt watch TV, so I'm not sure I agree with those experts about TV before bed.
Mostly I think your daughter is doing a typical two year old bedtime dance routine that, no matter what you do, she is likely to keep doing it. Go back to the toddler bed. Let her go through the stage and bear with it. eventually she will relax into a routine. However, one word of warning, she'll probably do it again and worse around 3. Its just a stage, but try to schedule her a little earlier, it will help. My son goes to pre-school where they nap from 1:30-3:30. On the weekdays it is much worse getting him to sleep. One the weekends he generally skips the nap and is asleep by 8:30. Good luck.
One word aside, you sound like a really great Mom who makes her little girl the priority. Good for you.
