My baby hit her head... [update x2]

Okay so my husband came to my work with our three month old baby and she’s been sitting up on the couch so I thought I could sit her on the counter top while I held her arms then let go she was finally sitting by herself! I was so happy then she wiped her head and she fell back! She hit her head on what I think is tile! She cried for a while maybe 5 mins and then she was fine. We got home maybe an hour later and she took a little nap now she seems Irritable I called the doctors and they think she’s fine but I’ve been google all night now and I’m really worried. I feel like a horrible mother and I don’t know what to do. I’m still going to take her to the doctors but I just thought I could get a little advice...Thank you i think I’m being extra paranoid I’ve been off and on of sleep checking on her she’s breathing normally she still eating a lot no vomiting no lose of motor skills and she’s been sleeping when I touch her head it doesn’t bother her but I do feel this flat part now and my husband says she’s had it but I don’t think I’ve ever felt it before this is making me sick to my stomach I’m just going to take her to the doctors when they open and I don’t care if they laugh at me I just want her to be okay I love her so much I don’t know what I’d do if something happened to her[updatedx2]So my doctors office was full so they told me to take her to children’s hospital so that’s what I did they didn’t see anything wrong with her but to put my mind at ease they did a X-ray and everything was fine nothing wrong apparently it was just her soft spot that I was feeling but now I feel a lot but getting the doctors to give me the okay via /r/Parenting https://ift.tt/2xkUeAH
