read the label on the different flavor choices. I don't recall them having flavors with egg the last time we went...so I only reminded them to get the separated toppings underneath the counter. Well, he came home and started complaining of a stomach ache, I asked him what flavor he had, went on the website, and sure enough it had egg. Luckily (?) that just resulted in benadryl, chased by zyrtec and tums a few hours later as he had a horrendous stomach ache for about 5 hours.
And my DH was there to boot! 
I remember your dd's reaction and subsequent anxiety very well. In one way, it's good to see that her anxiety has lessened. But you certainly don't want her taking risks either!
So yeah. I get it. But the thing is, she does have to make those decisions at some point... and by the time she is a young adult, they'll ALL be her decisions. Plan that trajectory.
