I took her home and she was fine the next day. But, on the second day around 4 or 5 pm she started vomiting severely, very large amounts. I immediately called the doctor's office ad spoke with an RN who informed that she had her shots two days ago and what her symptoms were. She told me to just watch her and if her symptoms changer or get worse then call back tomorrow or if necessary go to the ER. In the middle of the PM she woke with a T of 101.0 degrees. Still the next morning the same thing, so I called the MD again and spoke with an RN who informed me that I should put my daughter on a liquid diet with no milk and give her Tylenol for fever and if her sxs change or worsen to call tomorrow or go to the ER, but that I shouldn't be worried b/c babies do tend to have a rxn to the MMR shot but it is vitally important for them to have it. She only vomited for one day, she developed yellow diarrhea on the second day as well as the fever and that continued for approximately 7 -9 days. She also during this time was not active or eating and would barely drink any liquids at all and she would not do anything but none, lay on you and started into nothing like she was dazing and you could hardly get her attention. It was very scary. During all of this I called the nurse several times and took her in to see the MD twice and she told me that "it was probably just a virus b/c it had been long enough for the vaccine to wear off." So around the 9th or 10th day the fever was gone, but she still had "yellow" diarrhea still not eating well and she was beginning to drink more liquids but not normal, she was also not still playing and being as active as she normally was either. At this pint, I am very concerned, b/c my friend was telling me all kinds of stuff about side effects from the MMR. This continued for probably 6-7 more days. then, finally she began to eat a little bit and play and little more she wasn't as dazed and was smiling and talking a bit again. So, I started having a little relief, but she was still having yellow diarrhea. Which it took her about 7-8 more days before she was eating normal and drinking normal and playing normal pretty much. But her yellow diarrhea turned into constipating, which when it did come out she screamed and her whole body shook with severe pain and her belly was so tight and she cried so painfully. Now I was worried again b/c of all the side effects people were telling me about. So, I called the MD again, took her into the office and they tole me "I was feeding her to much milk and I need to change her diet, and to watch her and if she gets worse or if there was blood in her stool to bring her back in. So of course about 3-4 days later through all the screaming painful constipated bowel movements of yellow hard stool there was blood in her stool which I threw away and called the nurse who informed me to save the next one and call to bring her in immediately. So the next day she had another bloody stool so I immediately took her in to see the MD who looked at the bloody stool and said "she was probably still constipated from the milk and to start giving her 8-12 ounces of milk and say give or take a little, b/c it was not internal bleeding it appeared to be only form maybe tearing something while coming out b/c it was too big, but to continue to watch her and if it worsened to bring her back again." At this point, I had now been dealing with this for approximately 3.5-4 weeks. My daughter was starting to have bowel movements without screaming, but they were still "yellow" and went from diarrhea to hard back and forth. She was now eating, drinking and playing normal again. But she would still daze every once and a while. I realize a lot of people do that, but she did not until after she had the MMR, HIB and Chicken Pox shots. My daughter still has "yellow" bowel movements. She doesn't eat solid foods well, she does however drink quite a bit which was normal for her before the shots. She is not dazed very often only every once in a while like a normal person.
