ian could have bumped his head with out you knowing it. he will be okay. their little heads are just very sensitive to bumps. if you are still worried you could take him to the doctor to have him checked out but i think the bump will go away in a couple of days. all new mom's worry over scratches and bumps. if it doesn't go away in a few days, or it gets bigger take him to the doctor. i am sure he is fine. sending you huggs and blessings for ian.
