For Pearl: I once attended a conference on allergies given by Dr. Brown. She mentionned that when a baby has had a allergic response to a certain molecule, this baby's bowels become extremely fragile and permeable to a point that he would react to many other allergens (I think she mentionned for about three to four weeks following the incident). She suggested having mother breastfeed and watch her diet carefully to eliminate all possible allergens, or using Hypoallergenic ABM even though they are never garanteed to be completly hypoallergenic!!!
