My baby has started teething and I have tried EVERY possible thing to get him relief. Teething rings have been too hard on his gums, oral gel doesnt last long, etc.. I bought seedless grapes, froze them, and then cut them in half and put them into the feeder. He LOVES this b/c the grapes are hard & cold yet when he chews on it he gets the juice. Worked great for my prob!
