Link Steam account with EA child account

I know this is an old[er] thread, but I wanted to add another option to the thread in case it helps.

First, confirmation - After spoking with EA Support, they confirmed that you cannot link a child account to Steam.

My solution - I created a 'teen account' (needs to be 14+) and that linked okay...and also allowed me to add that account into my EA Account 'Household' to provide some visibility. So while not a child account, it is better than a full adult account.
