"Bottle feeding doesn't cause harm! It may not have as many positives, but that doesn't make it harmful."
Humans have evolved to need the protective elements in breast milk - they have immature immune systems at birth. If you deprive a baby of the protection that nature intends them to have then they are at additional risk of harm. As evidenced by higher rates of hospital admissions for infections in babies who aren't given their mother's milk.
But yes beast - you are right that when we're talking about infections and hospitalisation, it's a completely different issue for a 10 month old than it would be for a 10 day old. Which is why I said earlier in the thread that for me this story isn't really about the health benefits of breastfeeding, it's about the relationship between the mother and baby which the mother may feel is partially mediated through breastfeeding, and which perhaps is why she's so anxious about bringing this aspect of their life to a premature end.
"then I think it is proportionate and reasonable for the judge to balance the rights of both parents"
Actually the most important thing here is not the rights of the parents, but the rights of the child. The key key question is whether the father can maintain a relationship with his child without disrupting her current situation (of which breastfeeding is one aspect) to her detriment.
Have to say, it's very clear that people's attitudes to this subject on this thread have been very strongly influenced by the fact that they live in a culture where premature weaning and very early cessation of breastfeeding is absolutely the norm. Hence so many people seeing 10 months of breastfeeding as 'long enough'. Well yes, maybe it looks that way when you're bought up in a culture where normal term breastfeeding is as rare as hens' teeth.
