Grammar: Swim

I’ve swum with my son in the local swimming pool. I’ve swum with him only in the summer because it was an outdoor pool. He’s swum a little bit but he is still learning, so he hasn’t swum a lot. He’s swum because I have. I’ve swum because I learned when I was young and I liked it. My youngest son has not swum because he is too young. Maybe he will swim soon.
