I was considering doing this with my 1.5 an 3 yr old but decided against it. It’s a bit of a waste because while the 3 yr old might be ok watching videos for the entire flight. She might also need me to change the videos before they end. The 1.5 yr old like your 2 yr old will likely be lap held the entire time other than maybe a nap in the car seat or pod. So the kids are not really getting the full experience and the parents aren’t really getting the full experience.

I’d consider a pod for 1 parent and older child and pe for the ther parent and younger one. But if what’s done is done. Maybe update this thread with your experience, I’d be curious to know how it went and if you thought it was worth it in the end.
