How to deal with a 3-month-old baby not having a bowel movement for 15 days

Patient's question:

March 1st

Doctor's answer:

Suggestion 1) Drink more water, you must drink more water. You can add milk companion to formula or water, 1 pack per day. Formula and breast milk with calcium should not be eaten together; they should be spaced 2 hours apart, otherwise it may also cause constipation.
2) For breastfed babies, mothers should adjust their dietary structure, eat lightly, and drink more water.
3) Massage the baby's abdomen in a clockwise direction, twice a day, for 5-10 minutes each time.
4) If the baby has not defecated for multiple days, you can use infant glycerin suppositories or soap sticks. However, be a little gentler with the action.
