I was picking my 3 week old up out of his bed and accidentally hit his head on the sound machine thats connected to the side. im not sure if i hit his soft spot or not and he never cried and ate right after and is now sleeping but im nervous?

Have you noticed a bruise or swelling over the scalp? I doubt any serious injury to infant's head. In case infant develops unusual irritability, drowsiness, or vomiting, he needs medical attention.

Please follow up with your Pediatrician tomorrow. Watch for any lethargy,change in feeding pattern and vomiting. A virtual consult with Healthtap is available and the scalp may be examined. Remove any excess bedding and He should sleep on his back.
