At 4 months, some babies may pass stool only once every 5–7 days. If the stool is soft, baby is feeding well, passing urine/gas normally, abdomen is not swollen and there is no vomiting, this can be normal.
His weight gain is very good — from 2.75 kg at birth to 7.1 kg now.
At this age, total milk intake is usually around 850–1000 ml/day for his weight, but there is no need to force a fixed quantity. Breastfeed on demand and give formula additionally according to hunger. The amount of milk you can express with a pump does not accurately tell how much milk the baby gets directly from breastfeeding.
Prepare formula exactly according to the instructions on the pack. Do not add extra powder or extra water.
No need to start solid food before around 6 months just because of constipation.
Since it has already been 7 days, if he is uncomfortable or the stool is hard/painful, please get him examined by a pediatrician. Seek early medical attention if there is abdominal swelling, repeated/green vomiting, blood in stool, poor feeding or baby is not passing gas.
