Our baby loves them and we hook them up to her car seat, play gym and whatever else.You can hang these guys anywhere. Car seat, stroller, bouncy chairs, play mats. They have different texture teethers on each and they make the coolest sounds. I recommend ?These infant toys are adorable, soft and have tethers on them. Our 5 month old grandson still loves them!The larger, clip on rattles are cute and jingle when hit or shaken. The hand held rattles do not rattle at all. They do squeak when squeezed. The foot and wrist rattles barely make any sound at all. I am pleased with the clip on, wish the hand rattles actually rattled but ok for squeak toy, disappointed in foot and wrist rattles.I bought these for a disabled patient of mine. They didn’t last long and weren’t even used much. But they are super cute, soft & colorfulNice quality my boys like it, like the noise and colorsI specifically bought these because I thought they played music since there were music notes in the picture but they do not play music.They keep falling off the holder for the car seat or stroller but other then that great teething toys
