Hi!
I would bet with a little "work", your wife's milk will come right back up.

I never had any luck with "pumping" - In fact, I had
less milk when I tried that route... However, by our third baby, I was a "pro" and breastfed over two years.
Milk production works on a "supply & demand" basis.

The more often your daughter is allowed to nurse, even if it is only a little bit, the more your wife's body will reset and increase in milk production. Also, with the summer weather and your daughters increased solid food intake, your wife's body is just trying to regulate, so is shutting off a bit too much... I would definitely recommend drinking more water, tea, juice etc, and let the baby nurse more often.

At this age, momma's milk is still best, but if you go with goat milk, I, personally, would
not dilute or add things to it. We never noticed any constipation with our children (or us, for that matter

) when we used goat's milk (raw goat milk). Maybe pasteurized would be different??
I remember my aunt mentioned a bit of Karo syrup would "loosen" things up a bit if a baby got constipated, but I would just concentrate on giving her foods with a little natural fiber versus something sweet like that.
8 months old and still breastfeeding!! GREAT JOB!
