My 11 month old loves these (and has since she could first grab) but they do not work like they are designed. They are impossible for her to squeeze and they are hard for me to get them to connect and stay put. They are also a cleaning nightmare. They get very gross on the inside and I cant seem to ever get them clean. The directions tell you to drain them after each use but I can never get all the water out. If I can get them clean enough I will just stop using them in the bath.
