Constipation in 5 months 20 days old baby. He is combination fed ( formula once in a day). He trying really hard to poop. A small portion that came out is hard and dry. How can I help him?

A. hello infant formula milk can cause constipation in some babies and you can just try to add few drops of prune juice to the breastmilk and give for the baby and this will help baby to get relief from the constipation problem and make s it feel better and comfortable
