We got this as a gift when my daughter was 4 months old. She loved to lay and look at the blinking lights while kicking the spinners. She played with this toy the most and the sound didn't bother us, as you can set it to a lower volume.Now she is 13 months and plays with it in the sitting up position. She still loves this thing, playing with the balls, still attracted to the lights that she can now touch, but she doesn't understand the concept yet that she can put the balls up on the wheel and it will roll around and then roll down. So I can see she'll continue to play with this and not get bored any time soon.The downside is the assembly... it is a parents nightmare. But once complete, it was totally entertaining for our little one and still is.
