FP and Rider Swap

[PlutoIsHerFav]

We'll be at WDW in almost a week! We have FP+ booked, but in thinking about it, I'm wondering if I have the right strategy? We are going with our 6 yo and 2 yo, so we'll have to do rider swap on a couple of rides. For those that we have FP+, we booked for all three of us. However, if we have to do rider swap, does just the original parent and child have to have the FP+ - but still able to get the rider swap FP? If so, then that'd potentially free up the other parent for another FP+, correct? I'm thinking that might be good for the other parent to take the 2 yo on something nearby. Thoughts?!
