"My daughter was colicky and a bad sleeper. Her cries would wake up my son who was 21 months old at the time. It was rough dealing with a toddler and infant all day long—and then all night long, as well. I was at my wits' end. When she was about three months, she miraculously turned into an amazing sleeper. I was used to putting her down around 6 p.m., and her waking up at 9 p.m. to scream her head off all night. One day she just stayed asleep. I don't remember what time I ended up passing out. My son actually woke me up that morning, and I jumped up and ran to the baby's crib convinced something was wrong. But she was still sleeping and it was about 6:30 a.m.! Best. Sleep. Ever."
