Is anyone aware of any difinitive studies that link postpartum blood loss to reduced (or nonexistent) milk production? Is all of the information anecdotal? If so please let me know what you find, including amount of blood loss, how long it takes for the milk to come in (if the milk comes in), and if possible hematacrit levels of these mothers at discharge. I'm seeing a tremendous variation in the effect, but I would like to get a general idea so I can have certain mothers red flagged for automatic LC referral if they lose more than ??cc of blood.
