Hi! I personally think that Murray Callan is the best. That being said, my son started at Noonan at 10 months and did great. At that young of an age it is more about getting them to used to the water than anything and Noonan was great for that. They also let you swim once a week which was plenty at that age. However, when my son turned two I moved him to murray callan because I really wanted him to swim and I didn't feel he was progressing too much at noonan. Within a session at murray callan he was swimming across the pool by himself, it was awesome. He is now 3 and a great swimmer. We just started again with him and my almost one year old at murray callan and it has been great.they are definitely strict about their policies, they have to do 3 days a week their first session and then can go down to two in the off season. In the summer they have to swim 3 days a week, but, it works! Good luck!
