B.,
You poor thing! I can relate - my 10 month old just recently started sleeping through the night. Sounds like it might be time to move her to her own bed in her own room (or at least where she can't see you at night). If you don't already have a bedtime routine, you need to get one quick! We have a bath every night, brush teeth, nurse, rinse with water, read a short Bible story, read a short "night-night" story (Goodnight Moon & Bedtime with Night Light are our faves), turn the light out and say prayers in a soft, soothing manner. Then we sing the same little song that signals he's about to be put into bed. Now he starts yawning when we read the book, and although he sometimes fusses when I first put him down, he's soothing himself back to sleep now. (Other times he's squirming to be put in his crib b/c he's so tired.)
Your little one is probably nursing (I assume) at night to be close to you and to catch up on her time with you. At this age there is usually no nutritional need for her to eat at night, so you might want to start with the Feber method to help her learn to soothe herself back to sleep when she wakes. His book is called Solve Your Child's Sleep Problems. BTW, this method doesn't recommend you let your little ones wail for hours on end as you may have heard. :-) It's actually really humane and it makes sense. You might also check out the book, The No-Cry Sleep Solution by Elizabeth Pantley. It's more a collection of suggestions for bedtime routines versus a specific method like Ferber has. Still, it can be helpful if you want to build your own routine. Both will take work and commitment, but it sounds like you're ready to have your nights back, so you'll probably find it easy to do it.
I'd also start limiting her naps to one in the AM and one in the PM and no more than 2 hours each. You'll gradually want to make her morning nap later and later until she's taking one long nap after her lunch time. She may be sleeping too much during the day. You might also consider whether your nanny is contributing to the problem - it's pretty convenient for the nanny that your daughter sleeps so much during the day b/c it means less work! So, I'd make sure to set the schedule and make sure nanny is following it.
Another no-no is letting baby sleep after 4pm, although I can't say I totally agree. Sometimes my 10 month old is refreshed after napping in the car on the way home and still sleeps well at night.
Hope these suggestions help! Now is the time to get it under control, though, so you don't have an even tougher time when she's capable of climbing out of the bed at night. Let me know if I can help further!
Best,
L.
