9 month fell

My 9 month fell down a couple stairs and hit his head face first on the carpeted floor.

This is his first real fall and I’m so mad at myself.

He’s acting fine. Cried for a minute. Didn’t throw up. Didn’t lose consciousness. He is yawning though. Definitely going to have a major bruise.

What do I do? What else do I look for??

Please tell me this happens and I’m not a terrible mom.
