My daughter is 2 years old. She had constipation most of the time until our doctor prescribed her lactulose syrup. It really helps her if taken daily. According to our pediatrician she can take the syrup as long as needed, for months. I don't like the idea of giving her meds on daily basis for a long time. I give her fiber, pumpkin, fruits. She doesn't like prune juice. I am afraid if I stop giving her syrup she will have constipation again and feel bad.
