On new club seating I found it easier to take care/keep eye on grandson aged 12 with me in window seat and him across aisle to me. If it’s just 3 of you I’d be inclined to take window for yourself and the nearest 2 aisle seats opposite you. That way at least you can see both children and keep an eye on them and attend to their needs. If you put them in window seats you won’t be able to see them unless you get up but that might also work 2 window seats and an isle. I missed how old children were. Alternatively maybe WTP is better for you in this case. Of course always a chance they will change type of aircraft anyway!
just seen young children. They aren’t family friendly at all in my view, not with very young children. I wouldn’t be happy putting a 2 year old in them, but others might be.
