P.M.
Breastmilk will never go away. This kind of leaking is worse for Moms who breastfed less than 2 years, mainly because breastfeeding was biologically meant for at least 2 years and if you quit before, your body still wants to do what it was made to do.
The Mother's body will ALWAYS have a minimal production continue in the small chance it's needed again. The memory of these specialized cells is amazing, this is why re-lactation is so simple.
