With that said - there is a right way and a wrong way to sleep with your infant. Of course the PC police will show up and tell you it isn't true that women may be a bit more capable of it than men.
But you and I know it is true.
There is nothing weird, bizarre, strange , odd or abusive about sleeping with your own infant. But if a person is a heavy sleeper, has been drinking or doing drugs, has taken a bunch of cold medicine or is obese they shouldn't sleep with their infant.
Men are heavier sleepers than women when children are around- it is common sense.
What is inevitably left out of these kinds of stories is how many infants have been killed while sleeping in cribs. LOL Does that make sleeping in cribs dangerous? Not necessarily....but you don't place alot of pillows and junk in the cribs, you make sure the slats are appropriately spaced and you don't place them by a window where they can potentially strangle in miniblinds.
Co sleeping requires the same kind of common sense that is used with cribs.
