Parker swam half the total length of the pool by himself today without flippers. He took about 4 breathes to get there. His teacher was so excited, she looked up at the observation area and gave me a thumbs up before she gave him a high five when he reached the wall. Another mom said, "Wow, that was impressive. How old is he?" Her daughter is in the same class and looks to be about 6 years old. Impressive indeed!
