Question: 1 year old will not go to sleep?
Answer: Reasons Toddlers Refuse to Sleep Through the Night Something is bugging him—bright lights, loud noises or discomfort (he's teething, too hot, too cold, has a stuffy nose or itchy PJs, ate dinner too late, etc.). He's nosy and stubborn—doesn't want to go to his room because he wants to see what everyone else is doing.
