7 week old baby fell

Posting this anonymous bc I don't want judgment. we are all human. We all make mistakes. With that being said, my dumbass strapped my 7 week old son in his car seat while it was on the kitchen counter (like I'm sure a bunch of us do, like I do every time) & turned to say something to my mom when I hear a thud & my heart dropped to my toes. My baby was still strapped in (of course. These things are made to keep them safe during car wrecks for Pete's sake) he was crying & terrified. I am mortified. I feel like a terrible mother. Someone tell me a similar story. Someone tell me it is okay. He is alive. He is fine. It just scared him. I just need to hear it is okay... 💔💔
