Our son used to be a great sleeper. When he turned 2 we started putting him in a toddler bed to sleep and now he wakes up 2-3 times each night crying. We try taking him back to his bed and he screams. Since we have always rocked him to sleep we will do that and put him back but he will wake up in another hour or two. We try puting him in bed with us but that too doesn't work all the time. We are to the point that we feel tired all day every day. Does anyone have any suggestions?
