I guess the wooden block set and any toys or playground furniture/inflatable pools are kid like. Maybe sweet items too like the soft serve lamps or candy machines. I think racecar beds exist also. Pretty much anything bright and colorful would work with the theme though. You could also do a more pastel kid them town I suppose
i'm doing a little bit of kidcore on parts of my island and am using balloons, fruit furniture, colorful flowers, a lot of custom designs, some bug models and more to make it look cute. also i really like the knitted cat version of mom's tea set or whatever it's called
Elephant slides, jungle gym, toy box, plushies, block furniture, small kid bicycle thing, all the 'teddy' bears, balloons, egg furniture i guess? a lot of the mom stuff also, anything really colorful...
the fruit furniture for sure! when I think of kidcore I think of the three primary colors red, yellow, and blue, so you could go from there and choose other like colors that go with that theme.
