Re: Night Feedings
If you were staying home with him, I'd say "don't worry, just let him sleep, he'll make up for the missed night feedings by nursing more during the day." But since you're back at work, I think it probably makes sense to wake him for a dream-feed right before you go to bed. It will be good for his overall calorie intake, and good for your daytime supply... And I recognize that it's absolutely unfair that I'd tell a SAHM to "go ahead and sleep" while a WOtHM gets advised to be cautious and wake the baby! : duck
One reason why it's good to be cautious when your LO starts to sleep through is that when a baby goes 6+ hours without nursing, your estrogen level often rises high enough that you'll see your period return, if it hasn't already. A lot of moms have supply dips right before they menstruate, which can be a challenge when you're pumping, and of course there's the chance of pregnancy which almost always destroys supply (so at this point you need to be using contraception in addition to breastfeeding, if you're not doing that already and you're not okay with closely spaced babies!).
