Great ideas ladies, thanks! I guess I never thought about all this before and I've been lucky I haven't had any issues. If you saw my house you would know there's no dirt in here. I have the parents provide splashpants that stay here all year round and an extra pair of snowpants all winter. But I trust them to provide rainboots on rainy days, snowboots when needed and in summer I don't mind what they wear. But they do wear rainboots when it's wet outside because I always tell the parents the evening before what we are doing the next morning. The biggest issue I've had so far this summer is the abundance of woodchips that the children bring home from the park in their hats and shoes and cuffs. But I sweep and vacuum all of those away.
