Hi J.,
I have been there with my son. There is so much to tell you about it. If you don't believe in letting your baby cry it out, you may like to read this book: The No-Cry Sleep Solution: Gentle Ways to Help Your Baby Sleep Through the Night by Elizabeth Pantley, William Sears. It is very easy to read and follow. You can find in any bookstore and also in amazon.com you can find used books for very good price. It helped me with my son, that now is 2 1/2 and he sleeps really good.
Good luck,
M.
