don't worry, my baby girl has same problem when joing the 1st classs of pg but now, very active and show more patience to listen to the tutor. still not always willing to let the tutor touch her. also, they're still young so tutor said parent shd not push them, just the parent show their own passion to the game, to the class then time to time, baby wl learn and change their behaviour too.
ur tutor is right, let baby play more in playground. they may not immediately feel the atmosphere or play with other gor gor & jei jei or other same age childrens, but they can observe and imitate their behaviours. now,my girl like to following gor gor and jei jei then catch them and laughing.
agree, some childrens are very friendly but some are not. but if we watching them carefully, it is ok gei as i always believe it is a experience for our baby growing up.
If you just rely on playgroup which is one time per week, that's not enough. Better have 3 times of pg per week or 1 pg per week + many outdoor play with other children.
