My twins have been sleeping in their swing due to reflux for the past 2.5 months. I'm trying to get them back in their cribs. They napped in them fine..but last night I tried to get them to sleep at night...and they freaked out! They screamed forever! All during the night they were up crying. I don't know how to transition properly. I don't want them to cry like that...but don't know what else to do. I can't co sleep with both of them either. They have bath and bottle...then go to bed around 7:30-8. They recently started waking up multiple times at night again for some reason. They used to sleep through the night in swing...like 10-12 hours! Now they are up like newborns. So I thought it would be a good time to put in cribs since they get up anyway. Any advice?
