Greetings It is generally normal for a 14-week-old baby to go several days without a bowel movement, as their digestive systems are still maturing. However, the combination of not pooping, passing gas, and crying suggests your baby may be experiencing discomfort from constipation or trapped gas. You might try gentle leg "bicycle" exercises, a warm bath, or a light tummy massage to help move things along. Please consult your pediatrician if you notice a firm abdomen, vomiting, or if the crying becomes inconsolable

If the child has difficulty to pass motion he requires check up and advise.

Yes on and constipation is normal in infants.If no vomting and no abdominal distension then no problem.Continue breast feeding on demand

Consult with Pediatrician physically for further evaluation and treatment

If the activity is normal if there is no Abdominal distension if your baby taking feeds well then nothing to worry

In a 14-week-old baby, especially if exclusively breastfed, not passing stools for 3–7 days can be completely normal as long as the baby is feeding well, passing urine normally, gaining weight, and the abdomen is not distended. Passing gas is also common. However, excessive crying may be due to colic, gas, or discomfort while trying to pass stools. If the stool is soft when passed, constipation is unlikely.
