Funny thing was, even though I saw the benefits, I had some doubts about BW, fueled by the fact that most other moms I knew were co-sleeping and feeding on-demand. I started to loosen our routine, even nursing the baby to sleep sometimes...and guess what, he started waking at night. It was hard to get him back on track at that point because I had to re-train. But eventually Patrick was sleeping through the night again and taking great naps, and I learned a lot through trouble-shooting the sleep issues.
Whenever we go out, we always get comments on how happy and content Patrick is. We haven't followed Babywise very strictly, but the things we have implemented have definitely made our life easier!
