The only thing that should take more than a few days is the pregnancy, that is about 2 weeks IIRC, it sounds like you missed a step somewhere. After delivering the milk, you had to return to her, then a few days later, she would trigger the next step. Check your phone, the only other thing that might have been an issue that I can think of is if you were trying to do more than one thing at a time, that can really bug the game out right now, the closer we get to stability, the more problems we will see with the old code, and this is tied to some of it.
I could upload my save for having maxed my stats and finished mom and Jenny, but I bugged out Erik on mine, not sure if it was me or just an issue with this update, but if you want that, let me know.
