Re: 5-day old only nursing for 5-7 min per side
Nursing times vary widely even at the earliest ages. When mom has a ton of milk, a baby is more likely to feed quickly, because the more milk there is, the faster it tends to come out. Babies whose moms have significant oversupply often complete a feed in as little as 5-10 minutes.
According to kellymom.com, by day 4 you're looking to see 6 or more wet diapers per day, and 3-4 poops, which should be the size of a US quarter or larger. (Don't forget to count the poopy diapers in the tally of wets, since most babies pee when they poop.) Meconium should be gone by day 5. By that standard, it sounds like your baby's output may be just a tiny hair low, especially since the medium-brown color makes me think you're still seeing transitional stools (i.e. poops that still have some meconium in them).
Basically what I am thinking is this: today is day 5 so today's the day to be looking for the 3-4 poops and 6 wets. If baby makes it to that standard, awesome, no need to worry. If he doesn't, I think I would want to try to wake him a little more often to nurse and see if anything changes. Instead of letting him sleep for 2-3 hours, maybe try to wake him after 2. If you do that and nothing changes, at that point I'd want to call the LC and maybe stop by the pediatrician's office and pop baby on the scale.
My gut says that everything is fine, but I'm glad you're keeping an eye on this! Let us know how things go.
