Baby is 11 months, and at meal times will cry and act anxious if he doesn't get to taste some solid food. However, when I have given him solids, he would get constipated and have discomfort and crying bouts for days until I give him enough prune juice to get things going again. I've tried to make sure he has fibrous foods, and easily digested foods, but I'm not sure what to do here. Anyone have experience with this? Advice?
