HI!
My boys swim soooo well! We have a pool and in the summer they live in it! When they were like 9 months old I brought them kayaking for a 3 day weekend. I got lifejackets for them and it made MY life easier too. When they did swim I knew they were ok, and when I had to carry them the jackets had handles. When I had to lift them back into the kayak it was easier with those handles. Life jackets, just like for kids, give you peace of mind. I am a big advocate of them. I still use them on my boys when they keep going in the pool and it's been 6+ hours and I know they are tired. I put them on them just to be safe. (they NEVER are around the pool unsupervised though).
I'd get life jackets if I were you though, you won't regret it, you'll have them for years just in case and you'll have good peace of mind if they have them on.
Have fun!!!
