6 month old puking.

Ashley
My daughter is 6 months almost 7. Yesturday we were laying down and I look over and puke was gorging out of her mouth, i panicked and turned her to her side fast and then upward. It was everywhere and lots. There was no sign of illness , I spent 6 hours in hospital. Got blood work , but refused X-ray and catphetor... I'm worried and wondering where it all came from ? Could it be from eating solids ?? Will be taking her to her doctor. But just wondering if maybe I shouldn't be worried ? As this happened to anyone
