Please read up on “asynchronous development”. It is easy to forget that the kid who talks like a four year old is really still not even two, and has the emotional self regulation skills of a typical toddler (ie none at all), exacerbated by having to integrate so much stuff that they understand intellectually but not emotionally.

Reminding yourself of this periodically really helps on those days you want to scream in frustration in unison with your kids, LOL.
