Suggest Remedies For Lack Of Appetite And Weight Loss

My 2 year old tripped, fell hitting her head on the keen of the coffee table, not a direct hit more of slid down the leg of the coffee table. She had a knot on the right side of her forehead, I immediately put ice on it and it went down leaving a much smaller bump. Her pupils are normal not dilated, no fever or vomiting not is she crying. She s up walking, laughing, talking, playing normal things she does. I haven t let her sleep yet was waiting for 2 hours pass, once she does I ll check on her every 2 hours. Should I do anything else?
