My DS wakes up from his nap in an absolutely foul mood. Routine is always the same. Out in the morning, home for lunch, nap at 12.30/1. When he wakes from his nap he's just awful. Whines on waking, never babbles or chatters. I go in to get him and bring him downstairs for his cup of milk but he just starts screaming at me. And I mean screaming!! It was 15 mins today before he just stopped and drank his milk. Comforting doesn't do anything, in fact he'll generally pull away completely. I'm just completely at a loss as to what to try. Any suggestions?
