My older son is almost 4, and the baby is 2 days old. I have a double bed, and we do all fit(just mama and the babies) but I'm feeling a bit nervous at night and having trouble falling asleep. I've been sleeping in the middle of the kids, with the baby on the side that is pushed against the wall. No heavy bedding or pillows, and my older son has been surprisingly good about not moving around at night and staying in his spot. It's just nerves making it tough to fall asleep. I have a co-sleeper that goes in the bed(summer infant) but it is really big and doesn't seem sturdy, it makes me more nervous than going without.
I am looking into this right now: http://www.humanityorganics.com/humanity-family-sleeper.html
Anyone use this?
