How dirty are your daycare kiddos at the end of each day?

[Sassygirl]

Hi there. I currently have all 12-14 month olds in my care. Half are walking... half are not and are crawling still. No biggie. I have a huge fenced in backyard with all kinds of play equipment, slides, climbers, sand and water tables, ride on toys and a little cottage. Not to mention all the balls, trucks, bubbles, etc they play with. We tend to stay outside almost all day. Heck, I even bring my highchairs outside and they eat out on the deck and watch the bird and squirrel show while they eat and they LOVE it!
I have one parent of a crawler who seems to almost complain at the end of each day how dirty her daughter gets. Dcg LOVES being outside the most. She crawls all over the place and has a blast. That said, at the end of each day she is usually on her second or third outfit change and has dirty fingers nails and her clothes may be wet or mucky. The mom says almost every day at pick up "Wow, look how filthy you are" and I usually respond and say "But she had a blast".
I feel like there is such a short window with nice weather, lets stay outside as much as we can. Whats a little dirt?
What is everyones thoughts? How dirty are your dck's at the end of each day?
