I don't normally bother with reviews but I think this product is worth my time! (Hope you find the review useful).
My little girl is 97 percentile+ for height. I did a lot of research prior to buying this jumperoo. She is currently 5 months and I use a book to prop up her feet slightly so she has enough bent in her knees to jump. There is lots of room for her to grow in it given the 3 height settings. Fisher-Price really got the seat design right - despite her height she doesn't topple over. The seat is set deep enough and yet isn't so large that she gets lost in it (she can lean on the edges to support herself). The toys are fun - she really enjoys the keyboard, the red monkey and the sliding discs. The music isn't too annoying for parents either! The setup was super easy and Amazon did a great job getting the product to us in a timely fashion (as I couldn't wait to put her in it!).
We have an exersaucer that was a gift. The seat is so wide and shallow that it swallows my daughter in it (she leans too much and therefore topples over). The fact that she stands stationary vs being able to jump is a big difference. In contrast, the Discover and Grow is a wayyyy superior product, especially for my tall little girl! This is a toy that allows mom to step away knowing their precious little one is safe and fully able to enjoy/entertain themselves for a little while.
