It started to smell bad after the second wash, probably the rubber is deteriorating and sticking, I threw it away, I didn't sterilize it, only washed it as the instructions said

Although it goes in the fridge and my little one likes cold teething toys, she doesn't want this one from the first day of use. She puts it in her mouth for a bit and then throws it away. It is thicker (compared to others we have) and maybe it doesn't suit her. Also, it has a strange smell that even after 4 months of having it (although milder now and even after being washed again and again) it still remains.

Like all teething toys, it's fine. It doesn't break in the freezer. It's just not recommended to give it to babies completely frozen. When it becomes frozen, I let it warm up for a few minutes before giving it to them or I rinse it under warm water from the faucet. It doesn't stay cold for a long time, so I have to constantly change it for their sore gums.
