I bought Ada this little plastic pool at the beginning of summer. She loved this little pool. We stored it on the side of the driveway. Every morning when we got back from our morning walk she pointed at her little pool and grunted until I got it set up for her. You could find her swimming in it nearly every morning at 8:30!
Brother and Sister even joined in a few times! Although, I think Ada preferred to have the pool to herself. :)
