My 8 month old has been constipated ever since we started solids. She is constipated because she will not poop for a week, then she strains and cries. The stools are too hard. We have tried everything, backing off solids and starting over, lots of water, prunes/pears with every meal, yogurt every day. We can't seem to get the magic formula. We tried to figure out what makes her constipated by going to one food item only for several days, but it doesn't matter what it is---any solid is making her constipated. She is still nursing at least 5 times a day, often more, and taking a lot of breastmilk, so getting what she needs, but she really wants/loves solids, so we want to keep offering to her. Anyone with this issue and can give me some advice on what you have done and what works?
