Oh gawd... i'm like a germaphobic freak!!! Today during my moms visit in the clinic, I accidentally dropped my babys bottle on their floor. I sat it aside and forgot to mention it to my mom as she was still doing her check up. When we got back in the car she sat in the back with him and fed him that bottle without knowing. I'm feeling so uneasy now.... i dont want my baby getting sick or catching anything! What should i do? I feel so bad for my little guy. Why!?!?!?! Am i just overreacting?!?!?
