Hi all, Since the sugar in br. milk is lactose, it is very rare for a baby to be lactose intolerant. If there is foremilk overload you can see it as described as Catherine Genna said. However, be careful about putting the lactaid on the nipples - I had one mom who found that after a while, the lactaid really got to her and she had burning. Putting one drop in the baby's mouth seems to work just as well. Also, if mom is on antibiotics there can be a temporary problem as the antibiotics can make the gut more permeable, and the baby may fuss more with bf. Kathleen Bruce, as I recall, it was you, the Vermonter who got me, the Illinoisian, to join Lactnet. So, your tentacles are longer.... and longer.... :) JN
