Often floating poop means there's a lot of fat in the poop, which signifies malabsorption. This can happen with intestinal damage. If your daughter's intestines were damaged to the point of causing malabsorption (which it must have been since you said she wasn't growing properly), then it will take quite some time for the intestines to heal, a few weeks is not long enough for that, but it shoudlnt' take too too long with a 4 year old is my guess. Just be careful of all processed foods, and also hard to digest real food like beans and nuts which can be harsh on a damaged intestinal tract. Also be careful of food additives/dyes and MSG as these molecules pass through damaged gut and go through the blood brain barrier and can cause behavior issues etc.
The reason you have to also avoid soy is because the body can't tell the difference between the proteins of gluten, casein, and soy..they are only different by a couple amino acid sequences. Alot of people report that after thier body heals, they can sometimes add soy and dairy back in, but not gluten. Personally, i'll never add dairy back to my diet, too many other problems with dairy products for me.
I've been GFCF now for 3 months, and i'm feeling like maybe i'm also reacting to corn now...which will be hard because i've been relying on corn tortillas and corn chips with my hummus and guacomole! And to try to get my 8 yr old daughter who is also GFCF to stop corn will be really hard, but she's not improving enough so I think there is some other sensitivity and it's probalby corn.
good luck,
Liz

OMG talk about overwhelming! Thanks for the help and suggestions, guys. Okay so the gluten-free/CF part of her diet has been since the end of Nov 2007, saw immediate diet response then. GI symptoms, behavior, sleep and dark circles all improved very quickly. A couple months later the symptoms started to return, although I think she only really got a break from the hard big, floaty poops for a couple weeks. Thats when we began to use milk of mag. And let me just say that I am VERY careful but my house is not gluten-free. She has her own pots, pans, shelves for food, dog and cat food is changed, art stuff ect ect. There has been a few CC mishaps when hubby has prepared her food.... Oh and one more thing, since Nov she has gained 2 pounds and half an inch after not growing for a year!
So end of Jan I took out soy, did not notice a difference and her poops still hard, big, and floaty(although she goes every day whereas before she went every 3 days). So 3 weeks later soy back in but now I notice tummy aches and behavior are back, they were gone with soy gone. But the hard, big, poos just do not seem to go, unless she takes Mirilax(dr said to use). Can this be good to keep using? So I am seeing that I may also need to remove corn? OMG it is in everything too!!! Yikes. I guess the snack foods and cereal box foods are the biggest issues, especially for a 4yr old. I will try anything at this point because the poops cause her to bleed too........
Thanks guys!!!
