scared shitless

Hey mamas! My little girl is about to be 2 months old in a couple of days and this morning she made the highest pitched scream I have ever heard while she was waking up, she has cried while waking up a couple times before but never this kind of scream. I've never picked her up so fast, this really scared me. Anyone else's babies woke up like that before? Does anyone know why? 
I really hope that never happens again!! 😖
