We started using this jumper for my daughter when she was around 5 or 6 months. She loved it. She would jump for a long time and just laugh while she was doing it. She loved trying to pull on the birds overhead and jumping to make the sounds and music play. She finally stopped liking it when she learned to crawl. I would put her in it when her and I were the only ones home and it would entertain her for at least 45 mins so I could get some things done around the house. Great product.
