What are your thoughts on how the new freed babies will work?

I am personally over the moon happy with our freed babies and can not wait until they get here next year <3 But since we only had a glimpse of them and not much information I am wondering what everyone is thinking, how they will be incorporated into our existing game. This is my thoughts.

Had a big think and I think they might completely replace the babies, but they might work similar to Toddlers, where they have to sort of skill up (could be hidden skill) to do better, for example like the toddlers babble then talk, wonky walking then walking and then almost running and so on and on.

I am thinking they might start off as just drinking and sleeping and then perhaps sitting up and then crawling, they seemed smaller than the toddlers but not much bigger than our existing babies. I am so excited for them, I know they will be fun no matter how they are introduced into the game, just thought I would ask everyone else's thoughts as well :)

I do hope we get some news soon, even if just how they will be added to the game and perhaps another little clip of their adorable cuteness <3
