I recently put this together for my four month old. She is still too small to "jump" in it, yet even with her wiggling, the flowers will light up and play music. She is pleasantly surprised by the noises it produces. She also loves the attached toys. She is teething, so the teething toys are great! Plus, she has learned how to spin the noise makers for added fun. I do wish however, that the hanging monkey and rhino were some sort of rattle as that would add to her delight.
