It could be the two are unconnected , she may be so attached to you from all the attention about her 'bowels 'that's she knows that her yelling will get some of it.I am not saying she doesnt have a problem of some sort with the continual diarreha I do think that if you persist and they can do some more testing ...you will at least find out if she is allergic to some food or drink ..good luck
she's been on lactose free formula since we changed it when she was a baby. She has been eating fruit and veges since I changed her diet, rice crackers, gluten free pasta with a simple tomatoe sauce that I made. She has had dairy free chocolate with easter as well.
I agree with you about demanding testing, sounds like she may have tummy pain.So she is on formula and you have discounted any allergies to it.May I also ask what solid food she is eating I am wondering if she is in fact allergic to some food or milk ..?
