T.S.
S.,
My son (2 1/2) was also this way. He would moan and cry "Maaa Maaa". Here's what I've found that works for him:
1) We moved his bedtime up to 8 (from 8:30). This way, he is waking up on his own in the morning, and does so like clock-work, at 7AM. The "crabbies" were more prevalent when I had to wake him up rather than him doing it on his own.
2) Sounds silly, but I started bringing in my 5 month old in the morning to "wake up big brother". For some reason, this made Jacob smile and laugh (and baby Ryan, too). I let Ryan lay in the bed with him (I'm right there) and Jacob will play teddy's, give hugs, or whatever with him for a few minutes. That means a good morning for us every time.
You know, some people just aren't morning people (ahem, my husband). I can wake up and be ready to take on anything and hubby takes awhile. It used to annoy me to no end, but I've found that if I just give him like 15 minutes, he's fine. OR, I let the boys come wake him up with hugs and it starts him off with a smile. Lol.
