Hi Beki, I am sorry that your six month old baby has been constipated. However, 3 days is not enough to call it constipation as long as your baby is passing small and hard stool. It s good that you have given plenty of water and prunes. Kiwi can also help. But, the most important thing is to wait a bit longer. Glycerin suppositories are not recommended, instead can use anal enema after 5 days of passing no stool at all. Your baby is passing small stool but hard, and I understand you are worried about your baby. It happens for the babies to get constipated especially if they change eating habits. Furthermore, in certain points of their growing process, their intestines start absorbing all the nutrients in the food, finishing in being constipated. I d recommend to have warm baths by sitting your baby on a sink full of warm water to relax the anal muscles and help bowel emptying process. Next, massage his tummy especially on the left lower abdominal part to help the bowels move. Apply warm clothing on his tummy to ease the pain and bowel movement. At the end, I highly recommend to wait for a few more days to see a full bowel movement. If not, send your baby to consult a pediatrician to rule out bowel obstruction. All the best. Dr.Albana
