B.N.
My son had that issue when he was about 3 months as he was whiched from breast milk & formula to just formula. Try to gradually change her to 100% formula ( I used soy formula as well since he was alway sa bit gassy). You can always massage her tummy and lower back, Play the pushing leg game (gently push her legs up to her tummy with her knees touching her tummy and move them in a small circle, repeat), or if it gets really bad you can put a small amount (1/2 oz. or less) of prune juice in her bottle. That is what I did for my son as i didn't want to give him a sopisitory (sp?). I had to do it once and it was NO fun! It took him about 2 weeks for his poop to get back to normal. Poop that is the consistancy of soft clay, per my pediatrician, is ok. As long as they are going and there is no blood in her stool. My son is now nearly 20 months and still weird poop issues. LOL If you are really bothered by it, do call her doctor as it is what they are there for and it will give you peace of mind if the mommy's on here don't. Keep up the good work and know that you are doing a wonderful job!
