Baby randomly spit up/threw up everywhere


My 11 week old is formula fed. He very rarely spits up so this wasn't normal for me. I had him laying on his stomach on me while he was sleeping and all of sudden his stomach made like a gurly nosie and he started vomiting really bad like everyone on my sheets. He hadn't ate in over 2 hours either.

I'm a first time mom. Should I be concerned? Or do babies just spit up/puke sometimes? He's drinking a bottle now and seems ok. But the only time hes ever done that was when he was younger and would try to eat to much to fast.
