Choked on his food vomits everything the next day

My baby is new to eating table food and one of his terrible reactions lately has been to grab everything off his tray and shove it all into his mouth. Just yesterday he did it and choked for a little longer than usual before we were able to get it all out (coughed 3 times before we got it out) today now hes been vomiting his food and bottles. Is this normal or should I take him to the ER since the stupid clinic is closed it seems.
