I would like to know too ┑( ̄Д  ̄)┍ In Umineko Sou Days there is some childraising involved, also there's https://www.mangago.me/read-manga/yuri_natsu_kagaya_inn/ but that's pretty much it, unless you're asking about incest yuri. I used to know about few of those but i dropped them and forgot the names. I can try looking for them if you wish. As far as I know Best Friends is only yuri with two moms
Reccomend me yuri couples that have kids/are a family :) thankssss
