We will be going on a trip late this summer (in August). Jackson has been saying he would like to try going on a pump, but I was woundering if it would be eaiser to travel on a pump or on shots. Shots require giving a shot every time you eat, but a pump would require packing a lot more packaging. We are currently using pens, which don't require as much packaging. I am not really sure want to think.........any suggestions........thoughts.........we are going to be flying so I don't want A LOT of baggage.
