Would you be concerned about 2 year old child's development?

There can be many reasons why a child’s development may be slow. As you are concerned it would be advisable to make an appointment with a paediatrician and have her checked out. It may be nothing and if it is the earlier it is diagnosed the better chance of having it fixed. Some children can have problem with what they call motor skills. My niece had such problem and because it was picked up early enough she is quite normal now and she is 15 years old.
