hi wanted to ask my one month old girl makes noises while stretching i amnot sure that it is grunting as she take a good sound sleep please suggest is it normal

A. Their abdominal muscles are weak, and they must bear down with their diaphragm against their closed voice box (glottis). This leads to a grunting noise. They will grunt until they can figure it out, so it may take a few months for your newborn to produce a bowel movement or pass gas without grunting.
