The wrist is to come...this is his 3rd week of school (kindergarten) I have Peru much received a phone call everyday about his misbehaving in school he won't sit on the carpet with other kids sing songs with the other kids participate not a option he just won't do it he just wants to do what he wants runs around classroom they have special rules for him in if he's good he gets 5 mind to play w the numbers while other kids are learning....I already had a meeting with the guidance counsler social worker principal speech therapist special Ed therapist his teacher and an intern about what we could do to help him be more involved for one and to see about getting him evaluated BC they noticed that though my son if the youngest in the class academically he's more advanced then the other kids such add his math skills are phenomenal and he's the only kid in class that can write his first and last name and even though alt of it had to do w me giving him my own version of at homework along w home work from school but he catches on real quick but its easy for me to teach him BC its one on one....they were concerned also BC he sometimes talks in a3rd person like"Coley behave" or "Coley had"and the biggest thing is he didn't make direct eye contact i'm trying to tell him Cole plz participate in class please sit on the rug with the other kids do your work and he yesses me to death I an not w his father I am in a relationship WA great guy who wants my son to succeed I have a20 month old and lodes kinda up side down right now..I basically would like to know what do I do to help him pay attention and participate at school
