My main goal for the broken watch branch was to focus on the tiddies, and pregnancy was mentioned at times but not a big focus. I wanted to make sure to leave enough for the main branch.
Those were cool, I have to say Leah and her friend (I'm bad with names) are my two favorite so I was a little disappointed that they didn't get pregnant in that route because I feel being pregnant might give their growth a little boost and I even restarted the game and made sure to encourage pregnancy with the two of them
