Dear J., I can sympathize with you. That has happened with all of my kids.(we are a blended family of 6kids 18,14,13,12,8,4) It seems like just when you need them to look their best something happens and they get banged up at the worst possible moment. And, usually they do this right in front of you and you're right, there's nothing you can do about it except make it better. The guilt is horrible isn't it!! ;) But that's what moms do the best, feel guilty and then make it all better. Good luck with the walking!
