Q

How do you perform a developmental assessment?

A

Establish rapport and play with child. Use their name and get them to show you what they can do.
Test milestones they should have achieved by that age and work way up until they are unable to complete task.

Q

Why is breast milk the preferred method of feeding?

A

Breast milk contains antibodies that can help protect neonate from infection
Also linked to better cognitive development, lower risk of some conditions and reduced risk of sudden infant death syndrome
Less risk of obesity later in life
Can reduce risk of breast and ovarian cancer in the mother
