How do I get my son to stop...

How do I get my son to stop sucking on his hands and fingers? Every time I catch him doing it, I pull his hands away from his mouth but he puts them right back and he ends up choking himself. He's 2 months old.

EDIT: thank you ladies. Didn't know it was a developmental milestone. He's my first so I'm learning as well. 😊
