I was cleaning and my 3 week old baby was in his sleeper in front of his dresser and I made a huge mistake and dropped a tub of Vaseline on his head. I think it hit his soft spot and he cried for about 1 minute. I cried because i thought i hurt him really bad after i felt his soft spot. I keep worrying that i caused him to have a head injury. Should i be concerned and take him to the emergency room?
