Yes - 100%
Until we had our DD tested I honestly thought that she was NT. I have posted this before but I was always puzzled by the way that our daughter could do puzzles and assemble toys nominally for child many years older. I assumed that the manufacturers did this to make parents feel that their kids were smart.
So funny. DD came home in 3rd or 4th grade crying because she thought that the teacher was giving her kindergarten work to punish her. I don't think she believed me when I told her that she actually had grade level homework. DH and I were were clueless about what was going on until we had DD tested in 4th.
