Bedtime Fears of Abandonment

Does your child find a dozen or more excuses to keep you coming back into his room after lights out? My son recently developed an irrational fear of my leaving him -- to the point where he panicked if I wasn´t within view. Needless to say, this made bedtime very difficult. So I put a photograph of myself on the table next to his bed and told him that with my picture watching over him, he would know I was always with him. That helped him feel more secure and now bedtime battles are a thing of the past.
