Oral Developmental Milestones continued
From ages 2-4 years we will start to see many of the
signs of oral dysfunction become obvious such as:
Chew with closed mouth
By age 2 years the jaw, lips, cheeks and tongue
move independently of each other and the child
should be able to manage most foods in bite-
sized pieces and can chew with lips closed!
