Throwing up??

My baby threw up a lot. Probably all of his formula. It was 3 ounces. I think he just drank it too fast and then I had to lay him down soon after. So he threw it all up. There was very very light yellow mucus along with it. He’s 10 days old. He cried after it happened. But not for long. He seems perfectly fine. He also almost immediately fell asleep after.

Do you think he’s okay? I’m sure he’s fine. Babies throw up sometimes. And nothing seems off. I just worry 🙃😅

He’s sleeping now and seems okay.
