I'm trying to figure out if my 15 week old is allergic to something. He is exclusively breastfed. How long does it take for something I eat to get through to breast milk to affect him?


Also, can I bright red bum be a sign of an allergy? I know about the red ring, but this is on his bum cheeks and up in his thigh creases. (He also has the ring, but that's always there.)

My son is sensitive to dairy.  When he was a week or two old, we started noticing hives immediately after he nursed.  Knowing dairy is a most common allergen to infants, I cut that out and the hives immediately went away.  He never had blood tinged poops, but would at times have mucus present.  And he was really gassy, although I thought that was sort of normal.  


Fast forward a few months...a few weeks ago I ordered a sandwich and cheese was present.  I swallowed a whole bite before noticing I ate cheese.  I breastfed my son and there was no question he reacted to the dairy - he *screamed* and cried.  Heartbreaking.  From eating the cheese through to him breastfeeding, probably 2 hours had passed.


I'm treating that bite of cheese as a food challenge.  At least now I know he's still sensitive.


So yes, it sounds like something you're eating is bothering him.


Don't know about the red bum though.


Good luck to you!

It takes my ds about one to two nursing sessions before he reacts.

Wow, I didn't know it could be as little as two hours! That surprises me, but good to know. Thanks everyone!

my youngest would react at about 24 hours - (when she was tiny, if i had milk or cheese - 24 hours later she would projectile vomit) seemed weird to me that it took so long with my other kids it was more 4-6 hours ..

My DS was 24 hours after I ate the offending food as well.
