My husband and I bought this jumperoo for our 10 week old son. I know he is technically too young for this, but he is really developing early for his age. We set it up in about 10 minutes and it was so easy! We only needed a screwdriver for the compartment for the batteries. The rest was so simple to put together! My son was almost big enough, but his toes were just a tad too short to reach the ground, so we put a pillow under his feet. We put him in and his eyes just lit up!! He was so excited to be in it! He really enjoyed the spinning crocodile. I would definetly recommend this product! There is just so much for the babies to interact with! LOVE, LOVE LOVE!!
