Girls, the baby fell off the crib for the first time?????? I don't know what to do He calmed down and started smiling But I'm still worried ? Do we need to go to the hospital? Is he sleeping in his crib but gets next to me at night? He was all alone in bed this morning, but my husband left early today and covered him with pillows, but he still fell ?
