I love this jumper! My son is a big boy too and it looked like would quickly outgrow the height of this product. I thought, this can't be all, so I went on a search for the manual. (I purchased mine used so it was without). I found it online and ah ha! You can shorten the strap more than just the initial loop that is there. Under the instructions tab you can download the PDF. It may take a minute to figure out the picture, but basically you can pull the inside loop through, making it shorter, as much as you need to, all the way until the two plastic blocks are touching. That puts the seat at 2.5 feet off the ground, plenty of available hight for even the tallest little baby. I hope that the moms that wrote about height issues see this so that they don't have to turn in their jumper before it has truly been outgrown. Enjoy!!
