Everyone will let you know why your baby is not sleeping. Mine was not sleeping for the following reasons:
1.) not enough food
2.) gas
3.) mean mommy
4.) does not like his crib
5.) needs a pillow
6.) mean mommy
7.) he needs formula
Guess what none of the above are true. Your baby will eventually sleep thought the night when he or she wants to or needs to, or when the parents finaly let the baby sleep through the night. However, I strongly advise putting your baby in the crib when it is time to sleep!!!
