Hi, my 13mo boy wakes up crying from EVERY sleep/nap. He’s also an early riser. Been doing this as long as I can remember! We’ve tried the earlier bed time to make him sleep later, doesn’t work. But how do we get him to wake up happy? So many people advise leave him in cot till time you want him to get up, but he screams the house down. Desperate and tired - please any advice welcome
