Recently heard an interesting story from a breastfeeding dr. where I work. She's a black dr., which, I wonder, may also have contributed. She tells me that her baby (probably about 5 months old) was recently diagnosed with rickets. She was alarmed, knowing that her baby was getting the only breastmilk--the Perfect Food. She tells me she checked out the Breastfeeding Answer Book and found a reference to microwaving and fat soluble vitamins. She told her babysitter to stop microwaving the breastmilk and baby's labs have returned to normal. Mary Kling I.B.C.L.C
