I stopped breastfeeding my son due to him being allergic to cow milk, and at the time it was all I was drinking to "boost" my supply. So I stopped for almost 2 weeks, and im trying to get back at it again... Any supplements or teas any of you mommies recommend? I was only producing about 2oz from both boobs every 3-4 hours before... And unfortunately my soon never latched so I have to pump and bottle feed as well.
