I really really REALLY want free babies. Being able to carry them around and place them anywhere, tons of customization and things to do with them... I also want real cribs - for both toddlers and babies. I love cribs, they're so cute. I dislike the toddler beds but I know the majority loves them, but please just add toddler cribs as an option? There is no working mod for toddler cribs.
I also really really want the ability to teach a toddler how to walk instead of it immediately knowing how to when it ages up. I want them to start out by crawling and then you gotta teach them, like in TS2 and 3. It would be so cute!
