My 34 month old formerly textbook, easy-going toddler is suddenly becoming very grumpy, sensitive and easily frightened. He has always been a real laid back, well-mannered, easy sleepers so much that it often prompted comments/compliments from family, friends and strangers alike. He also has a very vivid imagination and has developed some imaginary friends and monsters in recent months. The imaginary friends are kind of cute, but the monsters are taking over our house. They have disrupted his sleep and can now send him running to me and clinging around my neck in the middle of play in the day. His former sleep routine involved climbing in his bed, I would cover him up, sing You Are My Sunshine, kisses, walk to the door and say "night night, sleep tight, 'see you in the morning light" and then I would shut the door. That was it. Houseguests would marvel at how easy this was. He would even shut his own bedroom door if I had somehow forgotten it. This past month, however, all bets are off. It started with needing a night light several months back, last month he decided he now wanted the door open, now he won't sleep in his bed unless I am there when he falls asleep or he begs to come into my bed. I have tried night lights, monster spray, playing with shadows (thinking that was what he feared) and even a reward system where he gets a new animal for his toy farm (Thank you Dollar Section at Target) if he goes in his own bed without a fuss and stays there all night. Nothing is working. I have asked him what he fears and he can never give me a straight answer. He points to something and I ask "Elmo?" so I remove Elmo. Then he says "that" and I ask "the diaper pail?' so then I remove the diaper pail. He keeps seeing these monsters that I don't see. Please help. How can I retrain him and get my son back? I'd like to do WI/WO but think that maybe I might have to do GW instead because he is so frightened.
