Fan Question

* Bottle feeding causing upset stomach *

So my daughter is six months and is formula fed. For the last two weeks she's had constant diarrhea that has left her with a bad rash. I brought it up to her doctor at her six month check up and he suggested to switch her formula to soy formula for a few days so we did, and while it did stop the diarrhea but it also made her super constipated. So we switched back to her regular formula and she's back to diarrhea and rashes. The doctor had mentioned regular formula might be upsetting her stomach, so this makes me wonder if this is the beginning signs of lactose intolerance? Any ideas of what I can do? Thanks.
