My toddler bumped his forehead and bump feels soft.?

My 3 year old fell from standing on a kids chair today and hit his forehead on the floor. He got a bump and we quickly applied an ice pack to it. I then called our Dr to ask if it was necessary for him to go into the hospital as he did have a bump that looks bruised in color and what concerns me is that it feels soft to the touch. She said as long as he doesn't show signs of a concussion or other concerning sings he should be Ok. I've been watching him the whe afternoon and he is acting like his normal self, but I still cant out my mind and ease. Is feeling the bump soft bad? The bump is not even that big and it is not the first time he bumps his head but it's never felt soft before.
