S.B.
I'm going the more simpler route and say he may just not be a morning person. My son wakes most of the time grumpy, and he's 2 1/2. What makes babies any different from us? Now, my son also likes to eat when he wakes up, but I don't believe he's hungry every day for the past 2 1/2 years. He has a twin sister who is so happy every morning, and a baby sister that is a hit or miss. Sometimes she is crying when she wakes, and sometimes just as happy as can be. She's usually happy when she has had a really good night sleep. That may be something else to look at. Is he sleeping good at night, and if not is he waking tired? That makes anyone cranky!! Good luck, and hope that helps a little.
