Oh my gosh so, so sorry for such a heavy loss!😢😢🙏🙏✝️ Unfortunately what is in the mother's system if breastfeeding can affect a baby. With how experimental all these vaccines are, it is just my opinion that probably the vaccine did affect her sweet son. The vaccines actually change DNA causing autoimmune disorders/ antibody issues so what affects the mother usually affects the infant with breastfeeding, this is just my opinion, not enough research done with adverse side effects of the vaccine. I would contact https://childrenshealthdefense.org and let them know what happened and they can give you further advice. Again hugs to all your families affected by this tragedy 😢😣😇🤗🙏🙏
