My son will be almost 6 mos when we go to WDW. We give him formula right now but Im not sure if the brand he is on is available in the US. He is on Enfamil A+. ( He gets regular breast milk too) Any DIS parents out there that buy formula know if its available in the US? Trying to see if its worth while to have it delivered from a grocery store to us while we are there instead of packing it along with us.
