I have identical twin girls who are 6 years of age. They are stuck together like glue which has never been a problem till now. There teacher has raised a concern to me that when asked to join in different groups they get very upset and can't concetrate. If one needs the toilet during class the other will cry. I have not really noticed at home because they are my only children and I thought it was normal and I've never tried to separate them as I feel it's cruel. I would really appreciate any suggestions please thank you x
