@schofield7 , you are correct in that when you file a form 2555 ( foreign earned income exclusion ), you are automatically disqualified from claiming child tax credit and additional child tax credit.
You can rectify this situation by not excluding your foreign income and taking foreign tax credit instead.
You can change from Foreign Earned Income exclusion but once you do that your new choice would be valid for five tax years ( you cannot change back for that period ).
While this doe not fair to me , I am still re-searching the code / statute and case law to see why we have this limitation on excluded income ( considering that when you exclude income, for purposes of residual income tax, your excluded income is included to put you in a higher tax bracket )
Hope this helps
