New Bedtime Needed?

Why do you have them going to bed so early? If you want normalcy..I would suggest an 8 pm bed time, for both. The kids are only going to sleep for around 8 hrs...(if your lucky)
No naps...for the time being..Gonna suck..but that's all you can do, and it's gonna be ugly for about a week. I know the oldest doesn't take a nap..but he doesn't get to go to bed either.
I understand "naturally"...sans..not screaming. But..if you want sleep and you want them to go to bed...they aren't gonna play by the Dr Spock rules..I suggest you make new ones...Dr Spock sucks

Start by moving bedtime (and naptime) back 15 minutes. Wait a couple of days and then move it back another 15 mins. Also make sure that your 3yo is at least getting some quiet time every day. She doesn't have to sleep but need to stay on her bed for 30 mins-1hour. This will help her winddown a little and be able to adjust to the new bedtime.

When my first son was around 1, and he started to wake up earlier and earlier, I basically used the same method I did for sleep training, but reversed. So, the first day, I would let him call out to me for 5 to 10 minutes, and gradually lengthened the time up until he'd sleep until 7am. Obviously, there's no guarantee this will work for your guys- especially the 3 year old, but it's worth a try. Is the 3 yr old still in his crib? If not, does he have toys in his room that he can play with until Mommy gets up? My son eventually learned to wake up slowly, and play with his crib toys quietly until it was wake up time.
(with that said, I am about to post a qu about getting my 8 month old to sleep thru the night :/ so clearly I'm no expert @ sleep qu's. lol)

Wow! Lucky you:) My daughter and son don't go to sleep or wake well -- their "natural" rhythm is 9-9 so it's a no-go. Maybe push their bedtimes forward 1-2 hrs and see if they will wake closer to 7 am?

"Healthy Sleep Habits, Happy Child," by Dr. Marc Weissbluth. Answered every sleep issue I've ever had as a mom of (almost) 8. Later bedtimes has never been a solution, believe it or not, even though that"s what seems logical. All my children went to bed no later than 7 and slept until at least 6 or 6:30 until they were at least 5, especially once they stopped napping. The book walks you through sleep training step by step, and is great to refer back to with each sleep issue that arises at different stages. And it often goes against conventional wisdom, but it has ALWAYS worked for me, no matter what age or issue. Good luck.

My only suggestion is to gradually increase their bedtimes by about 10 to 15 minutes every few days until you get them to the bedtime that you want. Then give them a week or so to truly adjust to the new times and see if that helps with their wakeup times.
I haven't dealt with this particular problem before, but I do remember reading an article in a parenting magazine regarding this and the above was the suggestion that I remember believing truly had a chance of working.
Good luck!

My 2.5 year old is having the same problem - waking between 430-530 every day! I used to have her bedtime set at 7pm (with a 1-2 hour nap during the day) but decided to move it back. She now goes to bed anywhere from 8-830, however, she still gets up around 530 every day. But I'll take 530 over 430 so I'm not moving her bedtime back again! She's never been a great sleeper so I think she only needs 10 hours at night.

If you have tried all the other options (leaving the door open or shutting it, using a night light or turning it off, telling them they have to get back into bed or stay in their room (if you trust them), or letting them get into bed with you) and they are still getting up early, I'd change their bedtime and if that doesn't work, then do what I have planned on doing - go to bed an hour or two earlier yourself!
