My 5-month-old baby has not had a bowel movement in 4 days?

Constipation in infants is not uncommon and can be caused by various factors such as diet and hydration. Encouraging your baby to drink more fluids, especially milk or formula, can help soften their stool and make it easier for them to pass. You can also try gentle exercises like bringing their knees to their chest and simulating a cycling motion to help stimulate bowel movements. If constipation persists for more than 7 days, it's a good idea to consult with a healthcare professional for further guidance.
