Is Jumperroo useful for our babies? I heard its fun. When can we start using it for our LOs?

my baby boy likes jumping and standing up. so i bought jumperoo for him and he enjoys playing by himself. my baby girl doesn't like jumping or standing so she hates the jumperoo. she will crys immediately when i put her into jumperoo. so i guess is depend on your child. p.s: they are 5 months old next week.
