My daughter, soon to be 5 months old, has not had a bowel movement in 3 days. She usually has 1 per day.

If a 5-month-old baby hasn't had a bowel movement in 3 days, and their general condition appears normal (no discomfort, fever, or fussiness), it may be possible to wait another 1 to 2 days to see if the issue resolves on its own. Stimulating the reflex to defecate using the tip of a thermometer with a little bit of Vaseline may help. If there are still no bowel movements after 2 days, using a glycerin suppository could be an option. If you have further questions, don't hesitate to ask.
