How about this one http://www.mangago.zone/read-manga/kazoku_ni_narouyo/
Not their kid tho
And maybe "Super Lovers". It really has family or brotherly vibes but there is age gap for seme uke.
Himegoto Asobi (one of the guys already has a kid from a previous marriage) (very yaoi)
Tadaima, Okaeri (this one is SO CUTE, though it is an omega verse one) (not yaoi)
Yozora no Sumikko de (the kid is adopted by one of the guys before they get together) (not yaoi really)
