Hi my ds is 4 years old he just started to talk not long ago. Just don't know if this is a asd thing but he have memorised over 30 long and short words so when I wright it down or he see it he will tell me what it is?!! Should he be doing this?! My other ds who is 3 have been diagnost with glut 1 and must now test my older ds doctor told me that there is a link between this 2 things ( autism and Glut 1)but that glut 1 is so rare ( Round 500 kids in the world) that normaly not a lot off doctors knows about it!!!!!!
