M W,
I suggest like one of the other mom's said calling a pediatric GI. I did that after 6 months of my son arching his back and not wanting to go poop. He was constipated and nothing I gave him help, prunes and all the other natural things.
The pediatric GI was wonderful, she did blood work and found out he was anemic and started him on MIRALAX, THANK GOD FOR HER! he now poops every day but I think it's best to ask a doctor about her problem and a nutritionist is good once you find out what's casuing her BM problem...
Best of Luck...
