I was "gifted" at school and put in a special GAT ( Gifted and talented class ) at about 8.... onwards...

I used to make jokes that DS would be special too.... but I have noticed so much recently especially.

he started to TT at 16 mths old
Can do ages 3 plus puzzles by himself ( 30 or more pieces) and quickly too like his mind knows where they go
He reads basic books ( dont know if its from memory or how he does this, although he sounds out the words I dont know ? )
He can count to 30
and from 20 backwards
say the whole alphabet
sings about 5 nursery rhymes word for word and he only learnt them recently... all at the same time

He responds to some things in indonesian ( we have been twice since he has been born )

and heaps more... You only really notice how clever they are when they are around older kids but are more switched on .... since ds goes to preschool nnow one day a week I have noticed he acts like a 3-4 yr old.... all his peers are still having trouble talking whilst DS tells stories all day and tells everyone what he did all week....
