When you should teach your baby to swim is a personal preference, but it’s never too early to get them used to the water, in my book.
That doesn’t mean you have to throw them into the deep end and hope they doggie paddle (although that IS one method). You can certainly take your infant into the pool with you and let him enjoy the water.
By the time your baby is a year old, she probably loves the water. Some kids will jump right in; others are a little more hesitant.
First things first: toddlers should wear swim diapers, not regular diapers.
Secondly, they should never be left unsupervised at a pool, not even for an I’m-just-running-back-inside-for-sunscreen second.
In the water, don’t rely on water wings, swim rings or any other flotation devices other than Coast Guard-approved life jackets.
You can start by having your child blow bubbles in the water without putting her whole face in. She can kick her feet and move her arms without having to swim. When she’s comfortable with this, she can mimic these swimming motions with you supporting her stomach and build up to actually swimming. For some kids, this won’t gel until long after age 3, but you can certainly get them comfortable in the water during the early toddler years.
