Love, love, LOVE these glasses. My son is three but on the smaller side and these fit perfect. They come with a strap that actually snaps in to the sides, plus a super sturdy case, free stickers for him (which he LOVED - they were adorable fruit with faces) and one of those awesome "Baby on Board" car stickers that looks like the baby from the Hangover. I'm thrilled I got a deal on this, but would pay full price for these any day.
