How many times a day do you nurse? Does baby get a top up every time, only some of the time, etc?
She gained about a pound in a month if you look at lowest weight, 7lb 2oz, to 4w2d, 8lb 1oz. That's about 4 oz per week which is a little slow, but this is also assuming all weight checks were done properly: the exact same scale, in either a dry disposable diaper or naked, and with 2 people looking and verifying the numbers. This might seem like a lot of hoopla over nothing, but different scales can show different numbers and that can cause unnecessary alarm. My son showed a LOSS of a pound using a scale that wasn't his normal scale. I took him to his normal scale and he was 2 pounds heavier than his last check. That's a 3 pound difference! Even if it's not whole pounds, ounces at this age can mean a lot. So, in the future, try to make sure the nurses follow the proper weighing techniques.
How long has she been skipping days between poops? At about 6 weeks, breastfed babies can go up to 2 weeks between poos! Yours is a little young to have started that, but it's not unheard of. The color and consistency sounds normal. If baby isn't straining to go, the poo isn't hard like rabbit pellets, and nursing frequency is high enough (10+ times in 24 hours), it's likely she just started skipping days early.
