Bruised feet?

so the other day i was changing mckenna, and i noticed she had what appeared to be a bruise on the top of her foot. it wouldn't surprise me - she has scrapes and bruises from all of her tumbles! as i looked closer, i noticed she had several of these "bruises" on BOTH feet. this is what i saw:

bruises? i think not. no, they are TAN LINES!! she wears croc shoes in the pool!

and an update on the gym sitch...i took her back last week, against her will, for only 15 minute segments. i didn't get the greatest workouts, but by friday she was playing with the kids instead of sitting on one of the workers laps. this morning i took her - and she told me bye! maybe this is a breakthrough...i can only hope, because i had a great workout!! :)
