According to work done by Cheston Berlin (he will be at ILCA this year), the amount of theophylline in chocolate does NOT cause a problem for a breastfeeding baby. However, MANY MANY chocolate bars might raise the level sufficiently to notice a reaction. As a choco-holic and one who is reactive to it (I still crave it at certain times; can you guess when?), I can tell you that a little may be tolerated, but a LOT causes serious GI reactions. (No need to be more graphic, I expect) Is there any reason to suggest that a baby might not also react when his/her level of tolerance is exceeded? %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %% "We are all faced with a series of great opportunities %% %% brilliantly disguised as impossible situations." %% %% definition of a lactation consulting service. %% %% Kathleen G.
