If your LO had something cosmetic that required surgery to fix , would you make the decision for them or wait until they were old enough to decide?

Our newest LO has fused toes on both feet. Most likely not a physical issue as he ages so no need for surgery. We aren't worried about itbut my parents asked us if we were going to have them separated and then said they don't understand why we wouldn't since it is a simple procedure and kids are cruel ( both are retired teachers). And my mom said it is a lot of pressure and possible fear behind him making that decision later on.

We don't plan to do the surgery, but curious what you would do? The more people we tell, I am getting 50/50 on those who had their toes separated or those that did not.
