Cathy Kaiser - I don't have a clue about the white blood cells, but I wonder if this baby is going to be diagnosed as "lactose intolerant" and put on a soy formula. One of my clients took a very different approach. She had given formula twice - once when her son was a newborn, then a few weeks later when her dr told her to stop nursing during mastitis. Her son subsequently became lactose intolerant and very fussy, but she opted to use otc lactase drops instead of weaning. She gave him drops before every nursing - more than the recommended #, but then human milk is mighty high in lactose. She worked part-time and found that his stomach "churned" the least with the bottles she left; she'd put the lactase in the night before, so it had plenty of time to work. Ruth Lawrence mentions lactase treatment as an option; this mother felt it made all the difference in the world. Baby was also highly sensitive to dairy, and mom read labels like a hawk - even avoided pills etc. that used lactose as a binder, figuring there might be traces of cow protein anywhere there was lactose. Mom still nursing 5 or more years later, baby (sorry - little boy) is very healthy; don't know current cow sensitivity status. So whatever the problem, if 2ndary lactose intolerance becomes part of it, there's a better life than soy formula available! Diane Wiessinger - on vacation as of now, so I'll miss 10 days of goodies.
