What is the treatment for a bump on the forehead caused by a fall?

I'm a paramedic, the best way to lessen a bump is to hold a cold cloth/compress on it for as long as the child will let you. watch for drowsiness and vomiting signs of a concussion. The quicker you put a cold compress on the bump, the better. As a childcare provider, I find the quickest thing is to grab a bag of frozen peas or the like from the freezer, wrap in a small towel and apply to bump as long as possible. Anyone with kids should carry a first aid "quick ice pac". It's a poly-plastic bag that when shaken, the crystals inside mix and create an instant ice pack. Never apply directly to skin; wrap in a towel, or paper towels, then apply to the little ones Boo Boo!
