I got this for my grandson for Christmas. He was just a little over 3 months, but I went ahead and got it because they grow so fast. He was too short to touch the floor even on the lowest setting, so we put a folded comforter underneath so he was able to make it bounce. He's a strong little boy and seems to NEVER stop moving., so I knew he would love it! My daughter was a little leary at first (1st baby), but loves it as much as he does now - he's entertained while bouncing in the kitchen while cooking. I would highly recommend.
