Any Suggestions on a Sleeping Habits

J., I responded to a similar post a few weeks ago. I pasted the repsonse below. Hope this helps.

we had similar, but not exact problems with our two, almost 3 yr old, son. It turned out to be enlarged adenoides. Call an ENT in your insurance network. Or I can highly recommend Dr. Jim Schroeder at Children's Memorial in Chicago (also takes appts out in Westchester). I won't go into details about adenoides and the havoc they can wreck on sleep, but either google it or look in Dr. Weissbluth's book which has a chapter about it.
Our son, had his removed about 3 and half weeks ago and the changes have been wonderful. He had trouble getting sufficient air because of his enlarged adenoides and this can cause sleep trouble. About 30% of children have this problem. It is quite common.

When my little one is on his back he wakes up a lot. We put him on his belly (now he puts himself on his belly).

Talk to the dr. about it, and consider having a sleep study done. This will let you know how much "deep sleep" she is getting, and possibly help the dr. to understand what is causing the restlessness.

Food sensitivities can rear their ugly heads in all forms including sleep problems. I would start by cutting out ALL forms of dairy whether it's in the formula (switch to soy), in her diet or in your diet if you're breastfeeding. If in a few weeks you don't see a difference, move on to eliminating gluten. She can really be sensitive to any food or chemical but there is a list of 8(google top 8 sensitivities) of the top problems makers and that's usually where to start. If she does indeed have problems, she may outgrow them as she gets older.
