Get up early to educate parents, nannies, grandparents, early education institutions, etc. What I want to say here is that it is unreasonable to rely on any method alone. Because grandma's education method every night is outdated and her parents are inexperienced, the general education level of nannies can't be reached.
Therefore, the most reasonable way is to focus on early education institutions (because they are more professional), such as institutions like Madison Early Education Center. If you have concerns, you can take a quiz first. I hope I can help you.
