My four year old child hides day and night

Has there been any recent Changes to the family (births/deaths/etc)? How long has it been going on for? Why do you have to feed her on the floor?

It could just be a phase (not that any of mine did this, including my autistic son), but you'd really need to see a paediatrician or a child psychologist to get an informed answer.

Is your child a cat?

Can I just say that kids are fucking weird without being judged because they honestly are. I've raised 3 kids & have been babysitting & stuff since I was 8. My niece went through a phase where she would only eat cheese slices & drink coffee. I thought she was going to die from malnutrition, but she was fine. She also went through a phase where she slept in a box for a couple of months (she was inside the house, but she'd move it around to different rooms & sleep on the floors). My cousin went through a phase when she was around 3 where she would bite ppl on the ass...hard. I've seen them go through so many phases that I think anyone born after 1990 is a different species of human. Eventually they mellow out and become slightly normal, but it doesn't happen overnight. I was born in the 80s and I think that the only reason kids seem so weird now is that parents give their children more freedom, and that's not really a bad thing. If a parent saw their kid doing what your kid is doing now during the 60s, 70s, or 80s, they probably would have reprimanded them to make them act "right", which wasn't really a good thing. Parents mellowed out during the 90s and stopped taking every little thing so seriously. There's probably nothing wrong with your daughter; maybe she's imitating a cat or something she saw on TV. God only knows... But she'll probably just go from one eccentricity to another within the year.

Btw, I was NOT the one that gave my niece coffee & got her addicted. That was MY mother -_-

Maybe she's just hunting Nazis

Small contained spaces make me feel safe. Maybe she feels the same. It's kind of like swaddling.
