My daughter is 3 months old, weighs 14 lbs and is very advanced for her age. This jumper is engaging, and allows her to tap the flower to get the jumper to make sounds, pull on the tree to make music, spin the flowers on the giraffe's neck, all while jumping. She is a little small to be in the jumper, believe they say it's good for 4 months up BUT my baby can hold her head up and steady, she's been rolling over since 7 weeks old. I put a blanket in back of her so she can be closer to the toys in the front, and I put a pillow under her feet as she is a little too short.
