My DD started y7 in September with only one boy from her old school attending. She's settled in well and has made a lot of new friends. She travels to school by bus each day (3 miles) but is collected by grandparents as DH and I are both still at work. DD has been invited to friends after school but because we don't know them, their families or even where they live we have said no. She is upset which I understand but we can't help but worry. I did say yes on one occasion but DH said if something happened it would be on my head so I started to worry and changed my mind. Are you being overprotective or just sensible?
