Brochure for Bilingual Families. What should we do at home to support this?

PUBLIC INFORMATION BROCHURE FOR PARENT
“Your goal is to design a brochure that could provide useful information to a parent. You have been assigned one question that a parent might have about child development.”
The question I got is:
“My wife speaks Swahili, and I speak Greek. We both want our son to grow up with the opportunity to learn the languages and cultures of his parents. What should we do at home to support this? Should each parent speak to the child in their language? Should we wait until he has first learned English before starting to introduce him to another language?
As you can see, there are three question in this scenario, please choose any TWO from above to answer.
You just need to answer the question and do not need to make the brochure and I will do it and present by myself.
In order to answer the questions, you should read and use at least 3 papers on the topic and then condense this material into a format that would be EASILY accessible to a parent. You need to decide for yourself what findings are important and well supported by the literature. These main points should then be communicated in a way that is clear and substantive, but not laden with experimental details. And you have to use the articles that I have uploaded. There are 5 in total, you are allowed to use no more than 4 of them. No additional resources is required.
Note that to identify 3-5 papers you want to read and cite, you might need to read the abstracts of 10-12+ papers A good strategy is to read their work and then look at the abstract of either additional studies on the topic by this author or studies they cite (or that cite them).
The brochure should be 500 words.
Requirements:
1. Use 3-5 empirical papers that I have uploaded. An empirical paper describes one or more original studies—it is not a book, chapter, literature review or opinion article.
2. Synthesize into easily understandable, informative text (500 words).
Note* this paper should be written from educators perspective who is going to answer the question to parents, so the words shoud be easiliy understand no complex terms. I have also uploaded two examples of brochure, you can have a better understanding about what kinds of language should be used.
And the answer should be have evidence from the articles that I have uploaded, you can briefly mention that study about in simple language.
For example, for one of that question that “What should we do at home to support this?” You have to give the reasonable evidence, e.g. early exposure to second language is significant, and age matters since in one study showed that children who xxx have better brain activity xxx, and parents who spend time and quality matters, so parents should talk, reading, for their children to what extend and so on…(which requires you to paraphrase the empirical articles that I have uploaded and give the advice.)
***Moreover, one article mentions phonological, semantic etc. component of language, when you mentioned language learning, do not forget to differentiate the different component of language.
In the paper, one page for one question and please list the question and cite the evidence.
Thank you so much and stay safe, let me know if you have any questions :)
