Re: talk to me about infants at the pool
We "dunked" our kids early, being big "water people" and we needed to lifejacket train our ODS at a few months old to go boating. HOWEVER, it's not for everyone, you really need to work up to it and make sure your LO is comfortable in the water (like training a dog, you don't have them jumping through hoops at the first session).
If I were YOU I would not dunk your LO, for a first pool session of the season. Splash, play, blow bubbles, and just have fun. Your goal in going is to have fun, not teach.
