Hi, just wanted to chime in really. Our DD2 has, after a year of vomiting and diarrhoea, seriously, imagine having the runs for a year!!!, been diagnosed with MSPI because her IgE levels in her blood were skyhigh (over a 100, 15 is normal apparently), but is not lactose intolerant (lactose is a sugar, she is allergic to the protein in cows milk, not the sugar). I have stopped breastfeeding and we initially weaned her onto SMA progress. We could simply not leave the house, she would happily drink a 7 oz bottle but it would come out of the other end bringing undigested food with it. It also had huge blobs of mucus and bloody streaks in it. She went badly aneamic and is being traeted for that now as well. She still gets really tired easily and halfway through playing will suddenly lie down for a rest for a while. I am gutted it took so long for her to get a proper diagnosis and at 14 lb at 13 months old I cant help thinking it has really interfered with her growth. Since the MSPI diagnosis she has also proven allergic to citrus fruit, kiwi fruit and strawberries. These make her eyes go puffy and she starts vomiting within 30 minutes of eating it.
There is no allergies on either side of our families and this has been a bit of a shock. I am a bit freaked out about the whole thing really and I hope she will grow out of it. And yes, she still has loads of cradle cap too!
We have had no reactions to the vaccinations she has had so far, or they may have been overshadowed by the MSPI, but I am a bit wary of the MMR which is due next week.
We are using Nutramigen 2 at the moment and her diarrhoea is much less frequent but not entirely gone yet, she does still vomit whole meals up occasionally too. I am quietly optimistic that she may grow out of it?
