I made a whole wheat meatless version of a baked ziti it came out delicious but I dont think the baby liked it. Because my tummy was hurting and I had sorry for the tmi but had diarrhea and i started worrying about my baby and if everything was alright. I'm super curious what it could have been from, maybe eating too much or too fast? Maybe I had too much cheese, or too much whole wheat? But I'm better now I just jump to so many conclusions. I don't know why.
