How often cani give my baby glycerin suppositories?

As needed but... If a baby has an infrequent and hard bowel movements, glycerin suppository may be used. However, if infant requires suppositories often, it is prudent to have baby checked whether or not he/she has something serious, e.g., hirschsrung disease.
As needed basis. Why waste money on glycerin suppositories! rectal stimulation is as good. Glycerin does not solve constipation problem.It only stimulates.
