My day sounds like yours The morning is spent doing a few structured play activities (playdough, art, water table, slime, outside, dance parties, tent play etc) and than after nap it's snack and free play. Usually an hour after nap most, if not all, of the kids are gone home so I don't do anything too messy either. This is when I put away dishes, sweep the floor, clean the bathroom and maybe get a few things out for the next day.

Once all my "work" is done, I sit down and free play with the kids until home time.
