My friend has been breastfeeding her daughter for 9 months now. Since the age of about 6 months she has been giving her a bottle in the middle of the night because the baby has got teeth and its when she is at her nibbliest. She rang me the other day a bit concerned because because a breastfeeding support person had told her that giving even just 1 bottle is enough to kill all the good bacteria in the babys tummy for the next 2 weeks and that it gets replaced with 'putrefying bacteria'. She wanted to know if it is true. I didnt have facts on it so could only say what I knew that there was this 'virgin gut theory' but that i didnt know much about the research behind it. We sort of reasoned that considering they start solids and have things like yoghurts etc from 6 months on that even if it were true then surely that would have happened anyway? In her mind though she is thinking that if its true and the effects take place for 2 weeks after then what is the point in carrying on b/feeding. Her theory being that if she had to substitute that bottle in the night with a breastfeed that she probably would have given up by now because she hates the bitiness.
I bow before all your expert opinions please.
