DD (2) is cared for by a childminder 4 days a week. She is happy there but i realised that now that older mindees have gone on to school or nursery she is the oldest. Other mindee is a baby around 6 months. CM is lovely and plays all the time with DD and takes her for walks and library but they do not attend any toddler groups. Does it matter at this age (only just turned 2) that she doesn't have contact with other children, do they need to be socialising or is it more important once they are a bit older?
