Lily had a doctor's appointment yesterday and at 13 months she is 29 1/2 inches and weighs 21 pounds, 4 ounces. Her height, weight, and head circumference are all at the 50th percentile now and she is healthy and developing well. However, for the past month she has been waking up crying many times every night and can't get back to sleep without nursing or coming in our bed. We think she is teething but we want to break these bad habits and help her learn to soothe herself (and get some sleep). If anyone has been through this, we could use your advice!
