I have a three year old niece that’s like a daughter to me and I’m trying to type her (if that’s even possible at this age). I have read that children rely on their dominant function a lot more than adults so maybe it is actually easier then?
She’s very curious, hands on, touches everything, licks everything, doesn't listen sometimes, charming, loves to be adored but only by her “inner circle” haha, acts like a cute infant to me but I think because she knows I always call her cute and smile at her, isn’t very open to many other people though, and is learning to play well with others but a few times, she has told kids that tried to play with her to go away and she doesn’t like them (oh boy). Her favorite toys are LEGO’s and those magnetic LEGO things, she loves to build things with them. She also enjoys watching random things on YouTube (kid friendly of course) and playing games that her older sister plays (Roblox, Meep City, etc). She has this insane need to use precise words, names, and order of where things should go based on her own personal logic or routine. She would always correct people when they use the wrong word or place things in the wrong place.
Being an SJ parental figure, I do often remind her of the rules (mostly for cleanliness) but she tries to sneak out of them, but follows some of them if she wants to. Other than that, I try to let her be who she is and recognize her need for freedom and independence.
