Our boy is about to turn 3 and since he was 16 months has done split nights. He'll wake between 1 and 4 and stay awake for exactly 2.5 hours before going back to sleep. Believe me when we say we have tried absolutely EVERYTHING we can think of. He is happy enough in his bed but calls out sporadically and I can hear him so I don't sleep.
Has anyone had this? When did it end? Did anything help? Absolutely desperate.
