Re: Enough milk and nighttime feedings?
Night-waking is 100% normal for such a young baby. It is your friends' babies, sleeping 12+ hours uninterrupted, who are the unusual ones. At this age, "sleeping through the night" is defined as one 5 hour stretch of uninterrupted sleep. So, unfortunately, it is not realistic to expect your baby to sleep more than that.
Should you feed your baby at night? Well, some people do night-wean before a year. There are several reasons why many people and I personally recommend against it. First, just because your baby doesn't eat at night doesn't mean he won't wake up at night and require someone to parent him back to sleep. Nursing a baby back to sleep is much faster than rocking or lullabying or back-patting or whatever. Second, he may need the calories at night, regardless of what his milk intake is during the day. The fact that your baby is not nursing particularly well during the day indicates to me that he actually needs the nighttime nursing sessions. Third, night-nursing helps keep your supply high during the day. You're very lucky to be able to pump 5-6 oz at a time, and night-nursing is probably part of the reason why you're having such an easy time filling bottles for the babysitter, and why you've managed to get your kid to such a good weight. And fourth, in order to night-wean such a young baby, you're going to need to let him cry it out- and that means a lot of distress on your part and on the baby's part until he gives up on the idea of getting you to give him what he wants and needs.
I can completely understand your desire for more sleep, though! I suggest checking out Elizabeth Pantley's book "The No-Cry Sleep Solution" for some gentle ways to get your baby to sleep more independently at night. And just wait- at a year, you can safely night-wean, and you're very close to that point!
