A milkintolerance reader sent us the following email:

I'm a mom of an MSPI kid who just turned one.  We're beginning reintroduction of dairy, and I wonder how other people have monitored their child's poops following reintroduction — just a visual inspection, or did you do guaiac cards (tests where you smear a sample on a card to detect trace amounts of blood)?  Just curious how in-depth others have gone to monitor the reintroduction phase.

I've never heard of guaiac cards.  We always did very careful visual inspections of our

childrens' diapers.  We made sure to have good lighting, and we poke around in the stool, by rubbing the diaper together to spread apart mucous streaks.

What about other readers out there?  How did you handle food reintroductions?
