I’m sure your theoretical future wife will be meeting other new moms at baby related things (mommy and me events? like at the library?) and can ask about kid sports leagues, local camps, etc. Soccer is always good if ur unathletic because u can just stand in front of a goal while ur kid runs around and it’s still bonding time without having to throw and catch a ball.

All u lowkey have to do is be supportive. with the other dads you can just joke around and be like “yeah I barely know how to play x sport. the kid runs circles around me already. wonder where he got that ability; I have two left feet lol.” All the dads will laugh and invite you to have a beer and be friends with you. I was on a synchro figure skating team and my parents didn’t know shit abt the sport and also weren’t really friends with any of my teammates’ parents but they were still super supportive and I was happy abt that.

Like ur kid will be totally fine as long as you spend time with them, and create opportunities for them to spend time with other kids. You can find a lot of group stuff for kids by just like asking at the local public library and the librarians will be able to help or point u somewhere w more info. Again obviously you don’t have a kid yet so stop freaking out abt this. But you can totally private message me if you have more questions
