Jumpers?! Which is best?😥

Tanya
Hi there mamas,
I have a four month old baby boy, and I will like to buy him a jumper, but I'm having a hard time trying to decide which one is better.
Is it for months  too soon to start them in that? What brand and why do you like yours?
Are the exersaucers better than the jumperoo? Or can I just buy an inexpensive Doorway jumper and have same fun for the little one?
Please share your thoughts!
Thanks a lot!❤️😉
