Hugs!! I am in the same situation. He had been doing great for months and months and all of the sudden, around 22 months, bedtime became a huge battle again. We think maybe he needs sleep. We have been doing the gradual withdrawal method. I now sit right outside his doorway until he is asleep. I hope to be able to stop sitting there soon! We have dropped a nap and yesterday and today he went down to bed like a dream. He was soooo tired,,,too tired to fight. We'll see if this is the key or not! Let me know if you have any breakthroughs!
