None of my own bf babies were bitten by mosquitoes, but mosquitoes do not like me or my father. I thought it was a benefit I gave my breastfeeding babies thru my milk because they got ate up after they weaned. Maybe it is a general benefit to all and not just my gift to mine? BTW I am really enjoying all the wisdom that I find here. Thank you so much. Diane Graybeal Director of Counseling and Education B.O.N.D. Babies on Natural Diets Newnan, Georgia
