Query: Wait to purchase for toddler, not baby

This product is not durable enough to be put in a baby's mouth (our son is 10.5 months old), but we put it away for him when he is older. The color started coming off of the numbers/letters. We do like how the entire back of the numbers/letters is a thin magnet so that no small magnet pieces may be swallowed. Not sure if they are completely non-toxic but should be fine when our son is ready use the toy to create words, etc.
