Patient discussion about grunt

Q. My baby is grunting and groaning while I breastfeed him. Is this normal? It only happens from time to time, but he makes these weird noises while nursing and I would like to know if it's standard behavior.

A. Does it sound like he is having trouble breathing while you breastfeed him? Does he make these sounds while crying also, or just while eating? All of these are things you should report to your pediatrician so you can be sure that the baby is not suffering from anything other than simple reflux while being breastfed.
