10A "Companion" with Infant - 11A or 10D?

Hey all!

I'll be flying KLM / Air France on the A350-900 from LAS to CDG, our first international trip with our (will be six-month old).

I managed to snag 10A on the recommendation of many for the extra room, and will be requesting the bassinet. Now the question is: which seat should my wife take? 10D across the aisle, or 11A behind me?

10D seems like it would make passing baby off a little easier, while 11A would mean we don't bother the person right next to us in 10H. I feel like I'm leaning toward 11A to keep him more "contained"?

Alternatively, we can switch seats and just be next to each other in the middle.

Anyone have thoughts on space/navigating with a little one?

Thanks in advance!
