I feel like a bad mom

I feel like the worse mom ever. This morning I put my baby on her play mat like I usually do and accidentally bumped her head on the floor. She cried but only for a moment when I picked her up she stopped. Then she had her 4 month check up today and had to get two shots and it took awhile for her to calm down. And when I was putting her in her car seat right after her shots I accidentally bumped her head again on the handle of the seat and she cried again for a minute or two. I feel like she’s going to hate me for causing her so much pain within a short period of time. I just want to cry. I feel like an awful mom.
