Meg LOVES water of any kind. You may remember this from last summer. Here is the daily (at least the last three sunny days) progression of her time outside.
She would just sit in the middle of this sprinkler being pelted with (freezing) water all day long. She usually has purple lips and chattering teeth when I turn it off.
Poor girl....she is perfectly happy with 3 inches of water to sit in and a 3' circular sprinkler. She needs a pool! She literally greeted me in her crib this morning with, "wanna put simsuit on?" (that is a statement disguised as a question.)
