Mum drank alcohol while breastfeeding

I had my first child earlier this year, and my mother has been spiking some of my food with a liquor that contains 40% alcohol. She and many other people in her community were led to believe that this specific alcohol would do wonders for their baby.

She even proudly told me that she drank this alcohol (without cooking it off in food) for the entire time she breastfed me - every night. I was completely gob smacked, and thought about the effects this could have had on my life.

It seems like this is a community thing, and all the people in this community have been doing it.
