My 9 month old gags and throws up that he is eating. He was coughing like something was stuck on his throat. Held him I've my arm and patted his back, and did a finger sweep in his mouth (it was hard as he fought me). He seemed fine after that, breathing and acting normal. Then I go to give him his Bottle and he got halfway through before gagging and spitting it up again. I checked again and still nothing, but he is crawling around, talking and breathing normal. I think something may still be stuck, but can't be sure. Any suggestions?
