We just took our babies to a creek at our local park. They've played in water before, but not where it was a little deep. I've just assumed they could swim, but today they made me wonder. When Earl got out in water that was a little bit deep, he kept holding on to my husbands leg. He wasn't letting go for anything. It was pretty funny:p Biscuit would go in the water but wouldn't stay long unless Dave was out there too, and he acted like he was scared to go too far. We would throw sticks out in the water. Earl would go after them ( in shallow water) and Biscuit would whine like he wanted to jump on in, but wouldn't. Anyway, the point is, now I don't know if they can swim or not.
