is it a must to do the 3day try for introducing new food? im working & bb in ifc mon to fri. that means at most i only get 2days to try a new food with her over the weekends :(

I believe ifc will avoid the food that have higher risk for allergies. Actually allergies reaction is usually immediate after trying the food or within 24 hours. So on the day if u see if there is any symptoms do check with the school what they have it in school and let the teachers know to avoid them. Shouldn't be much of a big problem.
