Geez...she may have a point about co-sleeping but I don't think there is a need to make a cot sound like a death sentence for your baby!

I think this statement: "Why do we not abandon cribs, where so many babies have died, and many more have been injured?" is a bit off too...I don't know the statistics but I'm sure babies have also passed or been injured in co-sleeping situations as well. Just like every other method of parenting, co-sleeping is not going to suit everyone, just like bub sleeping in a cot isn't going to suit everyone.
If you want to co-sleep fine, go for it and enjoy (we co-sleep occasionally if DD is really unsettled or wont go back to sleep at 3am and it is lovely but I do still enjoy having the bed to ourselves), but don't make cots sound like a death trap! JMO but provided the SIDS guidelines are followed there should be no reason why cot sleeping isn't as safe as co-sleeping.
