My 4 month old son loves this jumper! He didn't know how to jump when we first put him in it. It only took him about 2 weeks to figure out what to do. He loves it! All the toys are awesome! Just wish there were some buttons or something else other than a bunch of spinning toys. But other than that I'd recommend this to anyone! I also worked at a daycare for 4 years and all the babies I worked with loved it too!
