I have b/g 8 month old twins and I have been trying to get them on a sleep schedule for a few months now.  I have been reading several books, etc. and can't seem to get it quite right.  My son is a great sleeper and if was just him would probably have had himself on a schedule months ago.  It is my daughter that is the challenge.

Currently, they go to bed betweein 6 and 6:30 and take their naps around 9ish and 1ish.  We have made progress in that my daugther in that she will put herself to sleep in her crib for both nighttime and naps.  My son sleeps 11 to 12 hours a night easily.  My daughter, on the other hand, has been waking up around 4:30 every morning and will not go back to sleep.  I had been going in to nurse her, but since they are mostly on formula and solid foods now I decided to stop with the nursing a few nights ago.  This morning, she woke up a 4:30 and spent a full hour just talking to herself.  It was at that point that she started getting upset. 

So, my questions are: (1) what should I do about the early morning wakeups and (2) what does that do for my schedule the rest of the day?  If she wakes up at 4:30, I can't see keeping her up until 9 for her first nap.  I put her and her brother down at 8:00 this morning and she slept for 2 full hours.  My feeling is that, at this age, I can go more by the clock, but at the same time I don't want her to get overtired.  I am so tired of changing their schedules on a daily basis to try to find the magic solution.  Any tips would be greatly appreciated.
