My son got his cousin's swing as a hand-me-down when he was a couple of months old because he just loved swinging in it during a New Year's celebration. He used it until he was about 4-5 months old (crawling age) and he was starting to grab on to the side bars and stop himself (which he just loved to do and laughed lots, but I was worried he was going to flip himself out of it and would break it before future siblings could use it!). We loved having it as a hand-me-down because they are so expensive to buy for just few month's use! Anyway, hope this helps!
