EBF 11 month old weaning and traveling

This is kind of complicated but I am going to Italy with my 11 month old who is EBF and loves her food. I have 500oz of milk in the freezer so I finally stopped pumping while at work last week. Well now I'm freaking out bc I feel like my supply has dropped so much! Not sure if it's that or the fact that my baby doesn't nurse much anymore during the day. Anyway I'm nervous my breastmilk supply won't be strong enough while away! Going to start pumping again until we leave in a week. Anyone else feel their supply dropping while baby weans?!
