Food- sigh DS2 is actually better now we have stopped stressing about it. Some nights he eats a great dinner other nights he doesnt touch anything- but come 8.30 and he is staving. Last night he ate 2 tomatoe sauce sandwhiches (4 pieces of bread) and 4 slices of bacon, cold rice rolled into balls and a big slice of cheese but wouldnt touch dinner. We bake alot and that helps get them interested in food. 1 food that everybody devoures is the lactation cookies made with choc chips and about 2c oats not 3- its also great cause the batter is just as good for them
TT- I too would leave it alone for awhile, then offer a reward everytime she goes- a sticker, a marshmellow whatever works.
Sleep- that is tricky. Consistancy is the thing. We have walked the hard road here. Gone from everybody in 1 bed to 2 adults, now 2 adults and the baby with 2 boys in their room (they share)
We have a star chart. You get a star for eating your dinner, staying in bed (kinda)-perhaps falling asleep in your own bed is a better way to put it? and at the end of the week they can choose an outing, at the end of the month they can choose a toy (from a few choices).

your not alone
