bought our cosleeper yesterday! I didn't use one with my daughter, she just slept in my bed with me. but for baby number two, we are going to attempt the cosleeper.

Do these exist and work? My SO is scared of rolling over on baby if we cosleep, but I really want to cosleep.
cosleeping yes or no??? what's your views mommies
How many mommies cosleep? If you don't what's your opinion about it?
My cosleeping (bed sharing) mamas, does your baby sleep better at night ?and how old was baby when you started bed sharing?
