Re: 7wks all of a sudden low supply?
Most moms overproduce milk in the beginning. It's nature's way of making absolutely certain the baby (or babies) gets fed while mastering the art of breastfeeding. When a mom is overproducing, it is normal to leak a lot, to frequently feel full or engorged, to need to use only one breast per feeding, and to pump multiple oz of milk with ease if you're pumping. But after a while, milk supply decreases to meet demand very exactly, without a lot of extra milk left over to make you leak, make you feel full, or to pump out. At that point, many babies transition from feeding on one breast to needing both breasts.
So what you describe sounds normal. The decline in weight gain may just be a variation of your baby's norm, since growth is not a perfectly smooth curve at all times. Sometimes a baby will grow a lot in length and less in weight or vice versa. This is why you don't want to zoom in too close on the data. You want to look at the overall trend. As long as baby is being fed on demand (or at least 8 times a day, if baby does not demand enough) and is producing enough wet and poopy diapers, and mom is not experiencing some physical issue (like hypothyroidism, PCOS, pregnancy, or taking hormonal contraception) that can negatively impact supply, you can trust that baby is getting enough to eat even if there's variation in the rate of weight gain.
