Re: 4 month old slow in growth
This sounds pretty normal for a 4 month old, and to me would not be an indication of a supply problem. I'd suspect teething or an ear infection or a love of nighttime nursing before supply issues. Also, since she's eating so infrequently during the day, she's probably making up for those missed daytime calories at night. (Check out this article on reverse cycling.)
Starting about two weeks ago, she's been waking at 1am, 2am, 3am, 4am, 5am, 6am, and 7am before being up for good at 8am. She wants to eat every time she wakes.
Totally normal. First of all, pumping is not a good indication of how much milk your baby is getting while nursing. Second, it is normal for pumping output to drop after you have passed the first few weeks/months of engorgement and your supply has leveled out. When you were getting 4-6 oz of milk when pumping, you were probably making quite a bit more milk than your baby needed. Eventually your body got the message and started making the right amount of milk to meet your baby's needs, without a lot left over.
Also, I tried to pump the other night and I only got one ounce from both breasts when I used to get 2-3 ounces from each.
Since you moved cross-country, there's a possibility that the problem is not with your baby's weight gain but with the difference between your old pediatrician's scale and your new ped's scale. If your old ped's scale tended to overestimate your baby's weight, and your new ped's scale tends to underestimate, it could easily seem as if your child has gained very little in the last 2 months.
Your baby's diaper output sounds good, but if you're having trouble convincing your pediatrician that your baby is getting enough to eat, you might want to consider renting a professional scale. By weighing your baby before and after nursing, you can determine how much milk she's transferring during a feed. A log of feeding amounts can sometimes reassure a worried pediatrician.
