Family Purity (Taharat HaMishpacha)

What happens if a couple, Jewish but not observant, has a child born outside the parameters of the lasws of taaras mishpacha. The couple then becomes observant as does the male child. Is that child viewed with any negative eye?

Thanks, Rabbi Kaplan for bringing much spiritual depth and significance of this mitzvah. Great teachings. Thank You.

As always an erudite instruction. I look forward to your sermon each week.
