Why not? It can be cleaned up. They still get to enjoy their outside activities and I get the joy of watching their excitement. I mean I am going to have clean something up after them anyway.
When we have to bring outside in I just bring one outside toy in a day so that they concentrate on that item and enjoy themselves. Yesterday we had the water table in my kitchen. I simply laid out towels to soak up most of the water. The toys needed to be washed anyway so why not let them do it? They had a great time and I got to check something of my list!
This Crazy Life is mine and I love it!
