I'm currently breastfeeding my 10 1/2 month old. I've been having really sore nipples and I think it's caused from LO teeth when she pulls away. It's so bad that I can't nurse her on one side. I've been trying to pump on the side that hurts right before her feeding and don't get much milk at all. When she sleeps all night I'm engorged in the morning so I know I'm making enough milk. So my question is, is it ok to feed my LO goats milk to supplement not getting enough while I pump?
