When swallowing food or liquids and breathing at the same time causes coughing could this worsen or cause gastroesophageal reflux disease?
Yes, it is known by both names.
Actually they can - this has to do with the placement of the larynx - but around nine months, when nursing subsides (and eating more solid food occurs) the larynx moves lower down in the throat, occluding the previous passage of air and fluid at the same time, but allowing increased vocal ability. This gives infants the ability to breathe and nurse at the same time. (Page 80 of the November 2010 Discover magazine has a short discussion of this.)
