Young children don't as a rule play with other children the term used is "parallel play" where they play alongside others but not with others. The younger the better for socialisation as this is a skill that all children need to learn. Mothers Groups or play groups are a great place to start, especially if your child will be in day care at home by herself. FDC is also wonderful, because depending on state regs, she will be one of four or five children, and most carers only have one child under twelve months of age. As a carer myself, I find that the children who start care under ten months of age separate better from their parents then children aged ten to twenty months of age. I have a two year old who started with my in January, just began this week to play with another child (age 2-1/2) the elder child has been in care since 9m and has never had trouble been left by mum or dad
