and one that helps your baby sleep good! L used to be a super sleeper. STTN as of 8 weeks...until about 5 months. Then we moved him to pack n play, and now his crib. He wakes anywhere from 1 - 3 times per night. It's not horrible I know, but DH and I are sleeping horribly as a result. I know it may not be the mattress, but we are willing to try a new one. We currently have a used mattress that we got for free. I don't even know what kind it is. And since one of my friends had a similar problem with her baby that was magically cured with a better mattress, we thought we might as well try!

So what mattress do you have/recommend?
