ok, i am now a pro at feeding a child with constipation issues, as my dd has a bowel disorder.
for breakfast try porridge made on water, you can add a bit of milk after it's cooked, put brown sugar, some psyllium husks (get in your health food aisle) and some lsa powder. this can also be done on weetbix
snacks - offer fresh fruit, valia (or other probiotic yoghurt), some highfibre cereal, plate of fruit with sultanas and prunes
dinner - if she's a big pasta fan make spag bog, with 500g mince, 1 can brown lentils, 1 can of 5 bean mix, box of frozen spinach, and then whatever else you use to cook as normal.
apricot chicken is also a good one, get a tin of apricot nectar, and the recipe is on the back, serve with mashed SWEET potato and peas
basically, you can add beans and lentils to pretty much any dish.
also, make sure she is getting plenty of fluids, try to limit milk.
good luck!
basically,
