JMG - my little man's not the best sleeper either so i haven't got a lot of suggestions but a lot of people have luck with Infant's Friend as well. you can give brown sugar (1/2 teaspoon) mixed with 30ml of cooled boiled water, prior to or after feeds, 3 or 4 times per day, for a few days until a soft poo is passed. another thing you can do is a clockwise tummy massage. start at baby's lower right side of tummy (your left) and gently massage using circular motions, working your way up to just below the ribs, across the top of the tummy then back down the baby's left side of tummy (this follows the natural direction of the lower bowel). also you can help baby to bring his knees up to the tummy in a slow pumping action which may help facilitate a bowel motion. hope your little man gets some relief and sleep soon hon - take care xx
