a region in SE France, bordering on the Mediterranean: formerly a province; famous for medieval poetry and courtly traditions. Images of Mary Magdalene were hard to ignore when I began traveling to Provence, where medieval beliefs coexist with modern ones.
But for kids that love them, Johnny Jump Ups can be a great place to play. They are generally recommended for children around the age of 6 months (Though the official recommendation from Evenflo is 4 months.) until walking and weighing no more than 24 pounds.
If it is a bouncer seat that they lay in that vibrates and bounces that is fine now, But one that they sit in with their legs and feet touching the floor then not until they have control of their necks like 3 months. at 4 months I put my daughter in her johnny jumper.f by bouncer you mean Jumperoo (attaches over the door frame and baby uses legs to jump & bounce) then the baby should be able to hold up their head-around 3-4 months. It's never a good idea to leave the baby unattended in the bouncer. Neither should it be put up on a table.
