When we first found out we were expecting our third child, one of the first discussions was sleeping arrangements. We were going to get a bunk bed set that had the double bed on the bottom with the twin on top. Then my uncle gave us a set of twin-twin bunk beds. We were a little worried about Laura sleeping up top when she was only four, but she loved it and does great. Or she used to do great. Now she won't sleep up top. She only wants to sleep with O. Even if we put her up in the top bunk, by morning she's down with O. Last night we just let them sleep together and this is what we found when we checked on them. I think it would have been better for us to just get them a double bed!
