My 7 month old LOVES playing with my smart phone, so I thought this would be great for her. She does love chewing it, pressing the buttons, and watching the flashing lights. However, the volume is so low on this! I can barely hear it, and I also thought the volume would be better once I changed the batteries. Nope! All the other Fisher-Price toys we have have a great volume or at least an adjustable volume, but not this. I would return it to the store, but I threw away the packaging already. Very disappointed, and I will tell the other moms in my online group not to purchase this toy.
