Ditto on the "lots of fluids". My son drinks TONS of water. I notice he gets constipated if he goes a few days and doesn't drink his normal amount of water. As long as he drinks, we haven't had any problems with constipation. Hope some of everyone's suggestions work. PS - I knew applesause was constipating, but I thought any juice, apple included, helped alleviate constipation? Am I wrong? Please let me know. My son loves juice. I typically keep him to 3-4 ounces a day, but I should know if apple juice can add to constipation. Good luck.
