Nurses can be certified and have relevant qualification certificates to test, which has the widest effective scope, but early education does not necessarily have a qualification certificate.

Take early education as an example, brands generally train themselves, and the training certificates issued are only valid within the brand. Of course, some factions, such as Montessori, have a particularly wide range of training certificates, which can be recognized in many places.

That is to say, you are a baby nurse, you can do early education, and you can also do any work related to baby-rearing.
