for me i quite lucky that it was picked up when i was yougen. form parrten did not learn to walk to age 3. so it was parrtent at friast along with prescool. this have meant i allway had the support, with out it i would not be doing as well as iam. i think if any one notice sings of slow delvopment they should defanlty get it looked in to. i do belive that it should be commulary to be checked in someone at some point in there life. but i never had screening at my college it was an assment for support, but not why i had that support. they just read my peroius assment from my priamry school.
