Am I being normal?

I am a first time mom to an infant and I feel so overwhelmed today because I found scratches on his body (he gets watched by caregivers so I can work), the formula I’m giving him might be a bad one I just discovered on and on. I never felt so overwhelmed and protective about anyone. It’s making me crazy! I brought it up to my husband these concerns and he’s so cool. Makes me feel crazier for being so anxious. I just want my boy to always be ok it’s so hard because I know exposing him to the world means he’ll get hurt 😞 he’s safe in his bassinet sleeping like a beautiful little Angel. I just want to cry because I want to protect him from everything if I can...these are all new feelings for me..it’s hard
