First...welcome to the site.
Second, rather than try to summarize in one place, if you use the search function (left side of forums) and try sterilize, cleaning, etc you will find dozens of threads.
Just bear in mind, you are online so weigh what you find with common sense. Some will post details, and cite reputable sources; others are just people sharing what they do.
I hope you are able to find what you need, and feel free to ask any questions you or your family has during this time.
