The passuk says about someone who has children with a non-jewish woman:
??’ ???? ?? ???? ???? ???? They have betrayed G-d, by siring alien children
Meaning, that having shkutzim as children, is an entirely separate problem and betrayal of Hashem, from marrying a shiksa. I think it pretty pashut, that continuing to treat them as children is itself a continuation of the betrayal.
