My son is 22 months old, and he's just now getting the hang of sleeping through the night and is doing it more frequently. While I agree that you should try to start weaning him off the nighttime feedings (or at least narrow it down to a single feeding during the night), I'm going to tell you that if he doesn't sleep through the night until he's older, it's not that unusual. (I've heard stories about 3-year-olds who can't sleep through the night!) One thing to keep in mind, particularly since you're breastfeeding. Your son equates you with food (and other things, but mostly food). If you are the primary caregiver during those nighttime feedings, you may have to switch with your partner, because if you try to go into your son's room and NOT feed him, it's not going to end well. If your partner goes in, however - and especially if your partner does not have mammary glands - your son may be less likely to demand a feeding, and more likely to go back to sleep with just a quick cuddle and a kiss. Another thing you can do is to try to bulk him up before he goes down to bed. My son's dinner is at 6pm, with bedtime at 8 or shortly thereafter. At 7.45, he gets a sippy of milk (usually around 7 ounces). He is gently reminded to drink the milk until it's bedtime (and he can even drink it through his bath), right up to when he brushes his teeth. I've found that this sippy generally cuts down his hunger pains in the middle of the night - or at least shoves them back to 4am, which is infinitely preferable to 2am. Good luck! And sweet dreams!
