With the lesser availability of baby formula (junk food, poor nourishment), probably a lot of mothers are scrambling to find something else. First, I had forgotten but mothers CAN restart or start their own milk supply. Look for restarting breastfeeding, inducing lactation, re-lactation on youtube.
Secondly, ThePatriotNurse has an excellent video on this subject found here, sorry for the youtube link, couldn’t find another.
Third, one of my go-to sites for stellar nutritional information-- (www.westonaprice.org)--recommends two books that are FREE and downloadable, The Nourishing Traditions Book of Baby and Child Care and Nourishing Traditions. They can be found here and here.
Yes, I was one of them. It isn't rocket science for women to use their God-given equipment. It's unfortunate that our overlords have worked for many years telling women that what "science" creates is the best. Where have we heard that before???? What comes from breastfeeding is superior to what is produced by industry, for so many reasons.
