3rd grade growth spurt

C got her new ghillies today. Size 6.5. Her old ones, that fit until mid summer were a size 4. Granted, they were stretched, I'm sure, but I was not the only mom dragging out her check book to buy new ghillies this fall. Seems a lot of the girls C's age had similar spurts over the summer and went up more than one shoe size. Her teacher just bought her son new sneakers, running shoes and track cleats, and he's complaining about them being too small...

Then I remembered that I was my adult shoe size in 5th grade, which is only a year older than C is now (I started at 4 instead of 5). So I guess it's not that abnormal... just expensive!
