My son has had a couple bumps on the noggin from him learning to pull up onto things but nothing that would suggest a hard fall. He did fall off the bed once but this was after the blood started. The fall wasn't bad but definitely scared me to death! I took him to the doctor again yesterday and they sent me home with more stool collecting kits. Blood was confirmed today and they are referring him to a GI specialist. Now I just wait for my insurance to approve the referral and we'll go from there. I'm really hoping it's nothing serious that requires medication or surgery. By the way you didn't say whether you think probiotics are good or not, I'm curious what are your thoughts on those? I think I'm going to stop them for now until we get a dignosis as well as all solids.
