This is the first year David wore a costume for more than 3 minutes. It helps that he wants to play Toy Story all the time anyway, so this Woody costume had already seen some playtime action in the past week, long before trick or treating.
Norah wore this same costume last year and it still fit, so I figured, what the heck. Halloween is not my favorite holiday so I'm pretty loathe to spend a lot of extra cash on something that doesn't get much use. Plus it's still adorable. Bonus.
