A. That is because your child should be in either play group right now or it should be in nursery because by the age of 2 1/2 to 3 years a child should be in play group and 3 1/2 to 4 years is right age for your child is in the higher class everything is icing probably bouncing on top of the head to understand which is why the child is not comfortable you need to demote your child
