I don’t think it makes a difference. My toddler attends school since 18mo and he’s been fine so far. Probably down just once or twice for common flu that’s all. I give probiotics and vitamins daily
I don’t think it’s true. My girl goes to ifc and she’s on bm (she still get sick). So I feel it’s about the child own immunity. And I’m sure there are a lot of babies in Ifc that’s on fm.
breastfed baby must provided the mum nurse the baby at home after IFC then the immune system stronger. and it depends on individual immune system.
