Answer:
The author shows that the milk is like life to the boy.
Step-by-step explanation:
In this metaphor, the author talks about milk, and the feeling that the boy gets when he drinks it. It is clear that the boy was very hungry, as he felt a burning sensation in his stomach. This sensation, which is painful and most likely linked to death, started to die. The disappearance of it, therefore, can be linked to life, which the boy is obtaining from the milk.
