Ok, let's see if I can post now.

I do agree with Kriston that the higher the IQ the better an early identification, by the parents themselves or testing or whatever means.

Officially speaking DD4 is 'only' MG but I am (almost?) certain she is EG at least and that I have (by what I did or did not at home), as well thanks to her preschool, contributed to her underachievement.

For me, an earlier identification of DD's capabilities would have made a big difference.
