Gabriel...please sleep!!

Gabriel doesn't sleep. Not during the day - not at night. He takes one or two quick little pick-me-up naps during the day (15 min or so) and that's it. And he's up every 2-3 hours at night and refuses to go back to sleep without nursing or taking a bottle. We've even tried letting him cry it out (by accident a few times because the baby monitor was off). That boy will cry for hours if we let him. He wont take a pacifier and doesn't suck his thumb anymore. Most 7 mo old babies take 2 two-hour naps and sleep through the night. Not this guy. He's afraid he'll miss something. He's happy most of the time, but you can see his eyes drooping from exhaustion. Gabriel is getting his 3rd tooth (two on the bottom and one coming in up top). He is starting to love music! As soon as he hears it or as soon as you sing he'll start bopping around. He tries to clap, but can't quite coordinate it yet. His favorite song is "If you're happy and you know it". He'll instantly start to bop and attempt to clap. If you say the words "Bouncy, bouncy, bouncy" he'll start to bounce and bob up and down. He's starting to wave bye-bye. He'll flap his arm when you say it - even though I'm sure he has no idea why it excites people when he does it.
