If i had to be honest, that kind of manga is quite rare to find... especially for an omegaverse...

Really rare. Maybe try Totsugimasen Kara. Thats the only one i can think of right now but it's not nearly like Tadaima, Okaeri

Try this one. Don't let the cover art fool you. You'll be pleasantly surprised how it veers away from the usual omegaverse trope:

This has 2 couples I liked the second couple the beta and alpha. The omega and alpha were ok.

There is also this one http://www.mangago.zone/read-manga/koishite_baby_miyako_mimeko/
