Remember the mom whose baby had vomiting episodes after drinking frozen milk stored in thin, plastic bottle liners? Well, the mom was hesitant to try frozen milk again, but we discussed alternative storage methods in case it was necessary. She found, with the Holidays, that her milk supply has dwindled, and she had to use some of the frozen milk stored in hard plastic bottles (one alternative we thought we'd try). No problem. Today, her sitter had to use the milk stored in the thin platic bottle liners - she vomited again. Coincidence? Certainly not a scientific study - but an interesting case, none the less...
