Constipation in infants can often be managed by ensuring adequate hydration. If your baby is on solids, incorporate fiber-rich foods like papaya, pears, or prunes into their diet and offer extra water throughout the day. Gentle tummy massages and 'bicycle' leg movements can also help move gas and stool through the system. If your baby has not passed a stool for several days but is passing gas and seems otherwise comfortable, it is often normal, but contact your pediatrician if you notice persistent hardness or signs of pain.
