The effects of a food reaction for an FPIES child?
Vomiting, diarrhea and dehydration leading to possible shock symptoms, for starters...
The effects of FPIES for me?
Although  the list is long, the worst of it is the paranoia. I am paranoid. After  having friends over I spent a ridiculous amount of time sweeping and  vacuuming every corner of our home. I am paranoid that people think I am  ridiculously paranoid. I am embarrassed and constantly apologizing for  cleaning up food on our floor, or moving their kid's food further away  from mine at the table, and moving their kid’s snack trap up to a higher  shelf where mine can’t reach it.
The effects of FPIES for Ellie?
She’s  paranoid too. She happily grabs ‘her’ vacuum cleaner (the small dust  buster-like vacuum that we have) to help me attack every last crumb to  keep her little sister safe.
Growing up too fast. Ellie spends  an inordinate amount of time pretending that her stuffed animals are  sick and often, throwing up. She lines up plastic cups for them to puke  into, one after another. Sometimes, they throw up so much that they have  to go to the hospital. She is simply re-enacting what has been a part  of her life, I know, but it’s disturbing to see how blasĂ© she can be  about this. Ellie has been to the ER twice with Ginny for FPIES  reactions and once with Ginny after she tumbled down some stairs. Ellie  calmly waved goodbye once as I took Ginny to get some stitches after a  fall at a friend’s house. She acknowledges the ER when we drive by.  Ellie knows which foods are safe for Ginny and got very upset when I fed  her watermelon recently, even as I tried to explain that we were  trying a new food. The understanding she has of all of this is well  beyond her 3.5 years.
Fear. Recently, Ellie had a friend over  and that friend got sick while she was here; vomiting repeatedly before  her parents arrived to pick her up. It was the flu, but Ellie was in  hysterics, certain that the little girl was headed to the ER, knowing  that an ER trip for a puking kid is long and not at all fun.
The effects of FPIES for Ginny?
Again,  the list is long. Although the health issues and potential issues seem  like they should be at the top of the list, the worst and most  encompassing of it all, in my book, is the lack of normality. I find it  INSANE that she loves to say ‘cookie’ and points to the little table of  snacks that we see as we arrive at Ellie’s preschool 3 days a week, yet  she cannot eat a cookie. My heart breaks each time she daintily picks up  a tiny piece of something from the floor and hands it to me saying,  “Here you go!” Shouldn’t kids try to put everything in their mouths? I  doubt they should be worrying over every speck on the floor like my kid  does. And I desperately want her to get to eat what her friends are  eating – that special, delicately frosted, butterfly cookie that the  cafĂ© has for spring time. She doesn’t even ask.
All life  experiences change us and shape us. Life is change. What doesn't kill  you makes you stronger. I know all that. I get it. Truly, these effects  on our life are small. Other families certainly have it worse. Still, it  really bugs me that FPIES gets to shape my kids this way – that it gets  to shape me. I have to believe that we’ll all come out stronger and  better equipped at the end. I have to believe that, but it still makes  me sad.
