Answer:
According to Freud, Brit is in the oral stage of development.
Explanation:
Freud theorized that there are 5 stages of psychosexual development.
The oral stage is the first one, which goes from <em>birth to around 18 months of age</em>. In this stage, the <em>main point of pleasure is the </em><em>mouth</em> and it is the way the child learns about the world and his/her surroundings. This is why babies tend to<em> put everything in their mouths.</em>
In this case, Brit is exploring and putting everything in his mouth, biting, chewing and sucking in order to understand the world around him.
