Aisle or window?

On the return it's naptime so hoping she will sleep so will go for window for that one. But on the way there it won't be naptime so should I go aisle or window?

Only 1.5hr flight.

eta: ugh on the way back there are no window left except in extra leg room which means $20 more. And the only aisle left is all the way in the back. I think I'm going with the only one of two rows left that has a aisle plus middle left hoping no one takes the middle and or someone is nice enough to swap with me?
