Yes, there is a suppository version of a laxative for babies. One option is to use a glycerin suppository for children, which can help trigger bowel movements. It is important to note that suppositories should not be used as a long-term solution and should not be used for more than 5 days in a row. In addition to suppositories, you can also consider using Lax-a-day powder diluted in a bottle with milk. It is recommended to gradually introduce water intake and try moving your baby's legs as if they were pedaling to help stimulate bowel movements. If your baby does not have a bowel movement for more than 4 days, it is advisable to consult a doctor.
