Give her the miralax!!!! And cut down on the milk. My son is now 6 but he would only go poop on Sundays. It was not good. He would always clog the toilet. One Sunday he was so constipated that it blocked his bladder and he was in severe pain. He couldn't go to the bathroom at all! We had to rush him to the ER, it was so serious they took him immediately. Anyway, we got him unclogged and had to give him exlax and miralax to clean him out for the next few months. He now goes every day or every other. It was the most horrible, expensive poop that I have ever experienced. I don't want anyone to have to go through that!
