Hi. I'm Brian and I'll try to help.
How long ago was it that you created or last logged into the accounts? You must log into an account at least once each year to keep it active. At the end of the year, Microsoft permanently empties the storage associated with the account but keeps the account active. You must know the password in order to log in at that point. If after two years, you haven't logged in, Microsoft permanently closes the account and if the address ends in a Microsoft domain like @hotmail.com, @live.com, @outlook.com or @msn.com, the addresses are also permanently disabled and can never be reused. The exception to this is if there is a subscription associated with the account. In that case, as long as you pay the subscription, the accounts remain open. It is unclear if child accounts are considered subscription holders, but I suspect not.
You can try the sign-in helper. which should allow you at some point to specify a place to receive the code. https://support.microsoft.com/accounts-billing/manage/microsoft-account-sign-in-helper. Additionally, if you are a subscription holder, visit https://support.microsoft.com/contactus and choose the "Microsoft 365" button, which should get you to a chat session (eventually).
