Check out the Pasadena Aquatic at the Rosebowl.
If you don't like that I have a private teacher that will come to your house.
I did swim lesson at that age and my son never remembered anything, it was back to scratch at the beganing of the season.
I would start at the age of 3 and I would do private lessons at 5 days a week for 2 months.When you do it that much they really get it but starting the next season they forget all over again.
Good luck and enjoy the baby it goes by way to fast.
