Have just been 4 weeks dairy free (VERY hard work!) to see if it made a difference to ds2's eczema. His skin does seem to have cleared but several other factors have appeared in these 4 weks sono way of knowing if i was the dairy or not. So I am eating dairy today (ah, blissful cereals with real milk) to see what happens but just wondered how long it ould take for the dairy to get into the breastmilk and therefore notice any differences?
