I don't care if others co-sleep, but what happens when you have more than 1 or 2 children? We are about to have 3 children 5 and under and there is no way my bed would fit 5 people. It seems like co-sleeping is more adept to people who have multiple mattresses on the floor next to each other (for families with multiple children) or these families simply do not have many children (or their children are really spaced apart). My sister-in-law co-slept with her 3 children and they had two king mattresses on her floor. Plus, the kids all went to sleep at all hours of the night. She is literally in the same room as her children at all hours of the day (still to this day, 10 years later) with no time to herself.
I love to co-sleep, but I love my 1-2 hours of "freedom" more
, even if it takes 125 steps to get them asleep finally.
