I put my boy into ifc when he is 6 mths old. Due to both of us got to work n no one look after. My bog Don have much issue when go to pg as his personality is a very easy going person and well adaptable. I heard from my boy classmate which have the same issue as u. They try to put their kid in for half day first like from morning till 1plus and pick them back. Let them slowly get use to it and get along with friends and teachers. From there u slowly extend the hours. Hope it help u our somehow.
