She's clearly very smart. She's really good at math (she's in first grade but already has a good grasp of 3rd and even some 4th grade stuff). It took a while but now she's good at reading. She's creative, usually kind to others, VERY social (a challenge for both of us being introverted and shy to an extreme), and doesn't cause trouble anywhere.
However, every conversation with her is a challenge. She's stubborn, sticks to absurd ideas and gets really angry if we try to show her she's wrong. This is contradictory with her ease at math, but she has a hard time following logical things like if A -> B and B -> C, then A -> C, so there are daily verbal arguments with her that are very frustrating. It's practically impossible to have a 5 minute conversation with her without it drifting into nonsense.
Do you notice the same in your "intense"?
This is the core of the issue. But its still frustrating to see other children doing the things your child refuses to do or has a meltdown about. Especially simple things that you thought you could take for granted like pushing a baby in a stroller or napping.
