100 Baby Challenge with the Update

Though I am actually playing around doing this and either saying I need to get them to be able to sit up and crawl because base game infants can do that and/or discover 3 foods they like or dislike. Maybe. For fun. It is either that or unlock all milestones, and not really sure what they are or how many off the top of my head. So trying to think of what base game infants can do.

I also think for people that do not have the pack, maybe can aga up newborns right a way and play with infants until their birthday, might be a fair trade off.
