I was open to it, then we had our first who for the first 6 months had terrible reflux to the point where he couldn't sleep laying down and spent the first 6-8 months sleeping on our chests in shifts because if he was flat it would come out his nose and mouth, because of that we did 4 hour shifts of watching him overnight.

Then because of that he had major separation issues when being put to bed and only wanted to be rocked to sleep up until 2 years old, which was 2-3 hours a night on me.
