You might not even want to try to calculate how many sandwiches you’ll make over the course of your child’s time in school (hmm, five days a week for at least nine months per year over 12 years not including preschool — that’s more than 2,000 sandwiches!), but even more startling is all the waste that can go along with them. Reusable sandwich and snack bags can greatly cut down on that waste, and they add some spunk to lunches, too. Take, for example, snackTAXI bags. They’re made from cotton and nylon and are phthalate- and BPA-free. To clean them, rinse and air-dry or throw them in the washing machine and dryer. They’re sold at retailers throughout the area, including The Lily Pad of Towson and Little Sunshine Trading Co. in Ellicott City, and online. For details, visit snacktaxi.com.
