So, I just changed my 12 week olds formula. She is a spitter, she usually spits up half or more of the bottle. She was on Good Start concentrate, and I changed it to Enfamil thickened. She is now having hard stools, she turns bright red and has a hard time passing them. I noticed last night that there was a little bit of blood in her stool. on a good note she barely spits up anymore. Should I wait it out, or go back to the Good Start?
