So my 8 year old sheepishly told me he was the only child in his class that still goes to school with a book bag bless him...I promised him a backpack for September, what are the "in" bags for children? I feel so out of the loop, he doesn't seem to have a brand name in mind so perhaps 9 year olds aren't that fussy?! (So long as it isn't a book bag lol!) Any suggestions!
