Hi!
My daughter is 9 months, and some night we sleep all the way through the night and other we wake up 2-3 times.
We found if we don't do the whole lets get our P.J.s on right before we go to bed it works a little better. Eat dinner, Play, take a bath, get dressed, play some more, read a book, get a bottle and rock to sleep. If she has had a hard day or is cutting a new tooth I rock a little while longer after she has fallen asleep, then but into her crib with a cloth diaper that has my scent on it. There are some night, like the ones where she is cutting more than one tooth that she sleeps in the bed with me. When she sleeps in our bed she sleeps through the whole night.
My Mom had the expierence when she gave my younger sister Tyenol before bed to help with a fever, or teething pains that my sister would go into hysterics. we later found out when she was three that it made her see things that weren't there.
Good luck!
Cari
