I have 3 year old twin daughters.They are studying pre school. I have problem with the one twin. She facing slight difficulty in matching the pictures. If I show the two pictures of the strawberry is not able tell both are same. But she is able to identify the picture as strawberry. Also If I make her to sit for teaching, she will not sit and listen even for 10 minutes. How can I handle this ? Does she require any OT ? Experts, please advice.
