I was playing with my one month old DD ... Dancing with her, kissing her cheeks etc. i did move her around a bit but in no way shape or form did i shake her. & well she was smiling and almost giggling with me... And fell asleep...! Did i cause it? Did i hurt her!!!? Sorry if i sound stupid, i am a first time mom. I'm sure she didnt get hurt I just need reassurance! Tia!
