My 10 y.o. dd recently stopped sucking her thumb (yes, I know, I know), and that was how she got to sleep at night. Now, she can't sleep. She sometimes lies in bed all night (like last night) unable to sleep. She used to sleep well. As an infant, she used to nurse all night long. I'd wake up in the middle of the night, and she'd still be latched on from the time before. She's very oral.
Something interesting about this is that I frequently have insomnia. I sucked my thumb until I was in kindergarten, and then my parents used that nasty tasting stuff on my thumb to get me to stop. I wonder if I have insomnia because I don't suck my thumb. Could this be one of those weird genetic things?
Any ideas for helping dd to sleep? What we've tried in the past are: water fountain, relaxation CD, singing lullabyes.
