Morning C.,
No problem at all. Buy a little prune juice from the store. Then put it in a bottle and make sure it's room temp. of course. If you're using a 4 oz. bottle, put 1.5 oz. juice and the rest water. One daily bottle of a little prune juice and some extra water will help your daughter to have more regular, less strenuous bowel movements.
If you find as she gets older that she still has a bit of an issue, then I recommend Juice Plus. If you haven't heard of it, then let me tell you quickly. Juice Plus provides all the benefits of real fruits and vegetables. They have been dehydrated and for adults put into capsules...for children into gummies or chewables. I take them as well as my two boys. I started them on the gummies at two years old. My sons are very healthy and providing them with Juice Plus is great, because I can't always get them to eat as many servings of fruits and veggies everyday as they should. If you want more info. about the benefits you can go to pathasjp.com.
Good luck. I'm sure everything will be fine for your little angel. :)
