As an overproducer I average about 6 oz. a day to the freezer. At 10 months my kids were drinking about 24 oz. per day since they were eating 2 puree servings as well. That means I would need 8 days to produce enough milk for one weekend. The math does not work. Maybe she’ll be lucky and be a super-duper overproducer?
So you’d rather prevent your daughter from seeing her father?
BTW there are ways to increase what you produce.
