Has anyone had any experience of a breastfed baby being allergic to cows milk passed on via breast milk? My 7 week old son is showing a lot of symptoms of CMPA, I've been told it isn't possible until he's drinking cows milk directly but he's worse if I've had a lot of milk so it seems too much of a coincidence to me. I'd be really interested to hear if anyone else has had a baby suffer whilst breastfeeding. Thanks in advance
