Hi there, I hope this is the right place to ask this. I'm flying on a long haul from the US to Dubai on Emirates with two small kids (Economy), and I'd like to know if Emirates prohibits the use of inflatable cubes as footrests/seat extenders? Particularly in the bulkhead rows? I know EK has limitations on children's ride-on suitcases and more complicated options, but I'm just looking to use the much simpler beach-ball-but-square option. Not attached to any seat, just placed in front so my kids can lie down and hopefully thrash about less. Any insight would be greatly appreciated. Thanks.

EDIT: I've realized that EK actually doesn't allow "fly-tots" which seem to be basically what I'm asking about, so the question might be moot. But if anyone knows otherwise, I'd be grateful to find out.
