Hi, my lg has problems with constipation, I've had soooo much advice its unbelievable!! Breast milk is a natural laxative. Apparerently very diluted orange juice helps very well, water, apple juice diluted can help although eating apple/banana too much can have the oppisite affect, fruit/ veg purrees, pears or apricot especially, lots of fluids, anything you can get in, wheat-a-bix helps, water with a little demerera sugar in. Just do what you can n keep an eye on her and she should adjust, if not go see your dr, mine tried the more natural approach 1st, My lg was given supossertries, temp soulition, then lactulose but she's now on movicol and senna until she sees a dr at the hospital. I hope all goes well for you both
