Hi I feeded my 80 days old baby at 10pm, before while feeding him he choked and coughed for long a while , I am worrying if he could get aspiration, later on after a while I feeded him, will aspiration develop slowly, it's been 52 minutes since his feed, t do I wait for changes in respiratory breathing?, I feel he is wet crying, and will aspiration clear if I give nebuliser every 2-3hrs??how quickly can symptoms develop?, he burped (initially when he choked) he burped later on too when I feeded him after a while, currently he is mouthing and playing, I am fearing can he get aspiration it's past 52 minutes.
