Can couple who both have mild down syndrome be capable of raising children with help?

Doubt it would Hapn: While females with ds are capable of reproduction( with difficult pregnancies) males with few exceptions are not. For a male to be capable, i would expect him to be a partially affected mosaic ds & fertility would depend on the tissues of his body that has ds info. Having family support thru their lives is a great asset to anyone with ds or any impairment.
