At risk of getting flamed here;) , I really think we need to take all of our supposed "guidelines" (AAP and all the others...) and use our own critical thinking when we are looking at a parenting issue and not a health issue. For me, co-sleeping was much safer for my children. I am a VERY HEAVY SLEEPER! Now, you say, "how can a heavy sleeper say it is safer for her to sleep with her children?" I can answer that! I fall asleep anywhere when I am tired, including rocking chairs - especially when I am breastfeeding. I HAVE dropped a child to the floor while nursing in a rocker! I have NEVER dropped a baby from a safely positioned bed and I have certainly never rolled on my babies. I do sleep soundly, but I always wake in the same position WHEN MY CHILDREN ARE NEXT TO ME. Not when they are not. I have back problems and frequently change positions in my sleep when my babies are not with me in bed. When they are, however, I wake up in extreme pain from being in one position for two or three hours. So, although I truthfully do not really "enjoy" co-sleeping (due to the pain issues) for my children it is much safer in bed with me when I am tired instead of up in a rocking chair! I do always keep my babies between me and the wall, because my husband moves a lot in his sleep regardless of the presence of a baby.
Anyway, I have issues with using the banket "guidelines" of any medical recommendation board over critical thinking and individual situations. Look at all the times the recommendations have changed through the years!!!
