My 3year old daughter is extremely shy. She refuses to go into places she does not know and hides away if anyone she doesnt know well approaches her. She goes to nursery 3 times a week has done for 3mnths but she is that shy and nervous i have to stay with her. the first time i left her she was so frightened and nervous i was called back since then not left her as she still will not interact with other children unless i am by her side. Also she freaks out if anyone touches her teachers or other children. been told she just needs to socialize more but not geting better. Any advice?
