I was re-reading my sleep tips and realized that I have one more:
If your baby is uncomfortable (perhaps with gas pains?) when it is time to sleep, lay her on her LEFT SIDE. Did you know you can burp laying on your left side but you can't burp (without urping) on your right or on your back? It's true! Imagine what a relief it would be to a baby to JUST BE ABLE TO BURP!!
Now go ahead, drink some pop and lay down. You know you want to try it!
