how long to clear

[pastorT]

My ds is 4 1/2 mo.  We're still trying to figure out intolerances/sensitivities.  We're pretty certain about wheat and possibly corn.  I've been off dairy too since he was born since ds1 is mpi.  Anyway, I had to eat some matzoh bread for a passover meal the other night.  I only had about 4 bites, but his ecxema flaired up the next day so I'm pretty certain it affected him.  My question is, how long will it take to clear out of my system?  I have some frozen EBM but not a lot and I don't want to completely clear it out.  We haven't tried any formula yet so I don't really want to use this time to test it for the first time, but I feel bad BFing him if it's making him suffer.  Is there anything I can do to get it out of my system quicker?

Momentary pity party...I HATE FOOD ALLERGIES!! 

Okay, I'm done now   Thanks for the support and any suggestions

I Googled it and it appears that it depends on the food.  They say the milk protein is the longest and can take 1 to 2 weeks to get out of the mother's system, and another 1 to 2 weeks to get out of the baby's.  With food they say the max is 24 hours.  I don't know if you need to express some milk, if it stays in the milk, I never really breastfed.  Hope he feels better soon!
