When I was in school (yearrrss ago lol) I got a new backback each year. I didnt get the realy $$ ones that are meant to last years though, so they were needed.
For dd and ds I have always gotten them new ones as well. This past year I got dd a Jansport backpack, and its held up fairly well, a few smallish holes in the bottom, but nothing too major. Not sure if it will hold up for an entire year or not again though. Also, after a year of use, a new color/design is always nice, and they both love picking out their new backpacks.
So Im kinda torn as to do I get new ones even if theres are ok, might hold up, for another year, or just use them as back ups( also for their activities after school etc) So they would still be getting used, just not for school.
I supose this isnt realy that big a deal, just wondering what everyone else does, lol Thanks!
