Thanks for your help, Catherine.
His sleep routine is nap around 12:30 -3:00. bedtime around 7:30/8 waking anywhere from 6:30-7:30 (usually with 2-3 wakings in between). Some nights it's only once, some nights it's more than 3. The night I posted this, he slept through the night, but he has only done that about 8 times since birth. We do give him a bottle or snuggle with him to get him back to sleep just because it's easiest at the time and we both work full time. Need our sleep! I'm sure the milk has become a prop, but I'm confused as to why he doesn't always need or want it. Could it possibly be that he IS indeed thirsty and not just relying on it for comfort? We've managed to do a great job with pretty much everything else, except sleeping! This spirited child of ours can be most spirited in the wee hours of the morning.
Yes, his molars are coming in and his night waking has always been worse when he's teething, but he's never been a good sleeper. Goes to sleep on his own at nap time and bedtime without a problem. He's a happy camper and gives hugs, kisses and says "nu-night mommy!" Can't figure out when he can't put himself back to sleep in the middle of the night.
