I never did understand what the big uproar over co-sleeping is all about. Then again, I come from a family where co-sleeping and baby wearing is common place. I have six younger siblings who also all have children who co-sleep. I have Two NICU babies and was never told by any medical staff not to co-sleep with my children. My youngest son was what is referred to as a 'micro preemie'. He has had multiple surgeries, at 3 area hospitals, most of them at Boston Children's Hospital. The hospitals have always provided a bed for co-sleeping. Children's actually has mom and baby sized cribs. They actually have pamphlets in the wards about the benefits of co-sleeping with your child!
I find that the time i spend close with him keeps me in tune to his breathing (he has an airway disorder) I find that I am able to sense serious changes in his breathing and react to them where I might not notice until morning if he was in another room.
I would say, do what feels natural to you. If it was dangerous, it would not feel natural. As a mother you will know what is best for you and your baby. It has become to common place for us to ignore our instinct and follow the advice stranger gives us in a book.
Although I have to agree, I can obviously see the danger in a situation mentioned above, someone who was heavily medicated or intoxicated could hurt a baby while asleep, then again, someone in that state of mind could hurt a baby changing a diaper.
As with opinions, everyone has their own, and thinks their way is best.
This is just my two cents
Thanks
