Is this the first one? http://www.mangago.me/read-manga/after_the_child_sleeps/
1. http://www.mangago.me/read-manga/sorenari_ni_shinken_nandesu/ one of the best lgbt parenting manga i've ever read.
as for number 2, i don't think i've read that one. if it's full colored, try searching through manwha webtoons
If you find a yaoi manga like this, please tell me., I forgot one of my fav manga title :
1. A guy that are divorced . Taking care of his daughter alone. Working as a bartender. The seme is one of his gay customer. The uke (singe father bartender) never want to be close to the seme until the seme help him when his daughter catch a fever
2.a full colored yaoi about a couple that ran away from where they should be. A story about a son from an abortion doctor and a guy that has been accused. I think this story is from korea based on their names and the title... the end of the story is happy ending and they decided to have more journey...
