jumperoo question

Sam • 👶🏻 Sept ‘16 / 👶🏻 May ‘19
My 6 month old loves his Jumperoo, he'd live his whole life in it if allowed. Problem is the instructions say he should be able to touch the floor but it should be moved to the next level when his entire foot can touch the floor. Dude's entire foot is on the floor on level 1, but when we put it to level 2 he can't touch at all and doesn't enjoy it as much. Which is best to keep it on while he grows a little more? What do you do?
