Must be doing something right!

We had our 2-week appointment yesterday with the ped. Kinda late, as DD2
was 3 weeks exactly yesterday.
Her weight at birth was 7lbs 3oz. At 8 days old, her weight was 7lbs 8oz.
At 3 weeks, her weight was 9lbs 2oz. She's only been breastfed to date, I
have been pumping (although not quite as much the last week or so...) and
any EBM has gone right into the freezer for storage.
I guess something must be going just fine, seeing as the weight gain has
been fantastic - ped said that her weight gain has been double what the
normal and expected weight gain from birth weight should be, so yea, it's
all going good!
Taking pictures all day today, well, as much as possible, so I'm going to
see about putting pictures of the new giant baby who seems to be gaining
great weight!
