By 2½ years, your child will start to draw people that resemble a tadpole/amoeba - with arms and/or legs attached directly to the face. The face may not have any features.
By 3 years, your child will add features e.g. eyes and mouth. It is not until after the age of 4 that your child may start to draw a separate body.
Drawing is a way for your child to be able to show their thoughts and understanding of the world. Drawing develops through a number of stages and by 4 years old a child should be able to draw a basic representation of a person.
