Rebekah-
I came her to post my own question, but your daughter reminds me a lot of my DS, so I can't not chime in. DS is also a super early riser. Honestly, the only think that worked for us, or at least made it a little better, was to have a short morning nap. A longer morning nap, is letting your DD catch up on night time sleep, and just reinforcing the night wakings. What I did for DS, was no matter what time he woke up, I did not put him in for his first nap until 930. I see you are already there basically. But then I woke him up at 10 no matter what. If he was really really overtired, I let him go maybe an extra 10 minutes. Then He had a 3 hour A time, and his second nap was 1-3 on good days. He still went to bed early, because he wakes up early for the day, usually around 7pm. I know this will not work for all kids, but it might be worth a shot.
Now for all of you with DC who are already on one nap...DS is solidly on one nap now. Most nights he is sleeping 630-6/630. With some occasional days of very early wake ups. He only transitioned solidly to one nap around a month ago. He has not had any two nap days since then. The issue is that I cannot seem to find the right time for this nap. It used to be a struggle to keep him up until noon, so I was putting him down around 1130, and he would do a nice 2 hours. Now, no matter what time he wakes up in the morning, he is getting extremely hyper when I put him in his crib, and taking up to an hour to fall asleep. At first i thought overtired, because the first day this happened his A time was 520 am - 1130 am. But now it has happened repeatedly over a few days, and I think it might be UT. Or something developmental? He is doing well at night, which makes me think it's not OT, but then again who knows...DS is a late walker, and he has sort of just discovered that he can stand up in his crib and jump and make trouble. I thought this might be it, but I thought if he was tired, he would go to sleep.
Today he had:
620 WU (a little under 12 hour night)
PD at 1150
He only fell asleep 1220 or 1230 and woke up at 150
It is now about 620, and DH is starting his bedtime routine now
We'll see what happens tonight. He was generally in a good mood this afternoon, but his OT generally manifests as super early wake-ups. Do you think he's UT at nap time? Should I bump the nap to 1215? Is this a stage? Any advice is welcome, sorry for the LONG post!
