i have 4 kids the first 3 were never shy but the last was very shy up until the age 9 then it went away as fast as it came i just was very calm and never forced her into anything she didnt feel good about doing ,my best friend has 3 kids all of which are very shy her youngest has just finished 4th grade and the teacher says she only said maybe 5 words to him the whole year she is also very shy around me she has known me since she was 4 but my daughter she talks to alot but if someone else comes around she says not a word until they are alone again she has asked doctors they all say the same thing give her time ,i do believe this is true because i used to be the same way i never talked ,never did sports ,and hardly talked in school but now i am very outgoing have alot of friends and even make my kids crazy because i talk to anyone and everyone even strangers waiting in line ,i also have a cheerleading team,and help with softball,so just give him time try to encourage him but never force .just know you are not alone alot of kids are very shy my friend worries about it all the time but the kids will be fine .
