Do you have any idea what time the daycare puts him down for a nap? I'm guessing at least initially that's he's overtired (OT). If he's up at 5/5:30 and dozing til 7 but then doesn't go to bed til 9:30, that's a really long day. Most bubs his age do best on a 12 hr day or maybe 13 hrs, and that's with a 2+ hr nap. So I would definitely try to get him to bed much earlier. I suspect that's part of why he's waking early and waking during the night. OT bubs do not sleep well.
At 14 mos, he also is probably in the midst of switching from 2 naps to 1 nap (which is probably why sometimes he catches a catnap in the car on the way home), and that can mess up sleep a bit too. Is the daycare just putting him down for 1 nap? What do you do with naps on the weekends?
I doubt he's waking from hunger at night - it looks like he's eating well during the day. My hunch is that he needs the bottle to go back to sleep. It looks like he's never been an independent sleeper - you rock him to sleep? Then when he wakes at night, you do a bottle and do you feed or rock to sleep? You can teach him how to go to sleep on his own, but it won't be easy. Since he's used to bottles and rocking, I'd suggest using the gradual withdrawal method to help him learn how to go to sleep on his own. Here's a link on that:
http://babywhispererforums.com/index.php?topic=80750.0 I would develop a plan then for how to handle bedtime and the NWs (nightwakings) to begin to put space between rocking and putting him in bed. I'd also either start watering down the night bottles or cutting them out cold turkey. Yes, he will cry with gradual withdrawal - but you'll be there to comfort him. If you need to pick him up initially, you can do that, but the key to gradual withdrawal is that you do keep withdrawing - you keep intervening less and less until he's able to do it on his own. It will be a long process, but he's had 14mos of needing you to help him sleep, it will take him time to learn a new way of doing things.
