Baby hit her head

Em

We went over to my grandparents for dinner, my daughter was strapped into the highchair and I was finishing up putting her plate together. I guess she was pushing against the table with her feet, and she ended up pushing enough that the whole high chair fell backwards and she hit her head on the floor :( my grandfather who was standing near her, noticed just too late and wasn't able to catch her in time. She was scared and crying obviously, she has a bit of a bump on her head but she otherwise seems okay. once she calmed down, she ate her food and was back to her happy playful self. We plan on checking on her every couple hours throughout the night to make sure she's alright, but I don't know if we should take her in to the hospital to get checked out? she's 13 months old, so I'm scared there could an issue that we just don't see. but I might just be paranoid and overreacting because she's my first baby
