DD1 (2.11) started pre-school this week, has no problems with being left at all but when I drop her off she just seems to sit at a table on her own looking around at the other children but not really taking part. The staff say that she does play with dolls, draws etc but doesn't really interact with the other children which she does on playdates, also has a younger sister and they play very well together at home. Is this normal? I really feel that she needs the interaction of being around other children more but don't like the idea of my normally very chatty and boisterous DD being so quiet.
