I feel so terrible.

I just feel so terrible. Today is the first time I had to take my son to urgent care. He has been walking for around two to three weeks and gotten good. Today at grandmas he was walking around and fell and hit his head into her China hutch. He let out a loud cry and he got a huge goose bump so fast. I was freaking out. My mom hurried and grabbed an ice pack for his head and we decided by how it looks to take him to urgent care. I feel so horrible like I should have been right there with him to catch him but I wasn't. Nothing is wrong with him and his goose bump has went down a lot. I'm just so terrified of what happened. I just can't stop thinking about what happened.
