Recently, after a tough bout with teething, our 20-month-old began a habit of refusing bedtime with tantrums. A few months ago, we'd let him cry and it would correct itself...but now it seems he tries to climb out of his crib, and we're afraid he'll actually hurt himself. His bedtime is almost 11pm, when he falls asleep being held by one of us. There is NO routine anymore and it is driving us CRAZY. Please help!!
