I have been EBF DS since birth and am thinking of introducing the odd bottle of formula when I start weaning at 6 months. This is partly because I want to do an evening class one night a week and it would be good to feel I have a bit of freedom occasionally. Expressing simply does not work for me - I hate the process, get very little milk and find it really time consuming. For some reason, I am feeling really guilty about the prospect of introducing formula at all. Provided I continue to BF for most of the time, the odd bottle won't hurt after 6 months will it?
