my firstborn fell off the bed at 3mth old but she is ok. then, during her first few attempts learning how to walk, she hit her face between the eye and nose area on the corner of the wall. she only cried alittle. but after few days it left a bruise on the area. it takes 2months for the bruise to disappear. all along eating, drinking and activity seems normal. but if ure worried u can check with the doctor.
Please bring your LO to see a doctor. Get LO throughly checked to have peace of mind. Take care
