Braving the 100 babies Challenge [Support group started]

I have been thinking about this challenge too. But a little nervous after having an infant in my other gameplay lol. I did see someone suggest 10 milestones and then letting them age up and I think that might be doable, but they do seem to age up pretty quickly on their own. My infant never got to crawling or pulling themselves up. Never got to try first foods, except for one! It was rough lol
