Cosleeping.... ..Is a bad idea in any case. The risk of what we used to call sids (now suid, sudden unexpected infant death) is much higher with cosleeping. In fact, both cases of suid in my practice were in cosleeping families.
Quit co-sleeping. More than a hundred kids die in the us yearly due to co-sleeping. Mothers roll over & suffocate their baby or the kid strangles in the bedding. The american academy of pediatrics has issued a warning on this issue. You shouldn't love your baby to death. Same room, yes, same bed, no!
