You can remove pregnancies with cheats. Also, I believe that that's only for one path of her quest line.That feels like a missed opportunity to have new events and challenges (mainly to child support draining your funds), especially if we can get a full harem ending where we marry ALL the girls. It also means we can't get the non-pregnant scenes with the girls without reloading an older save. Hell, Samantha's main quest line REQUIRES her to be pregnant in order to reach max LP. Just put in a daycare (maybe with a sexy babysitter who admires your virility when you have enough kids) and let the mothers name their kids if coding new names is too taxing on the program.
Also I kind of understand why Andrealphus hasn't added in a daycare and why Andrealphus probably won't. Simply put game is made by a single programmer (and one artist?) It's most likely not as easy as just putting in a daycare, there's probably a lot of things that would need to be changed, which means a lot of re-coding. After completely changing the UI a few months I doubt Andrealphus wants to do something like that again.
