Seeing as we are in the realm of personal anecdote, I'll add mine. My daughter did self-wean at 11 months. Having been an avid feeder, she had no further interest. She walked early and wanted to be eating dippy egg and soldiers in a high chair and roar around chasing the cat. I struggled on trying to feed her at bedtime until she started stealing her brother's milk cup and trying to climb into her cot. So it isn't true of everyone. And all this 'feeding strike' and 'mature milk' business strikes me as over-theorising something that happens for some people and not others.
But what really bothers me here is CC being slated for telling the truth about her experience of breastfeeding. Part of the problem with the breastfeeding lobby, it seems to me, is that all views must be relentlessly positive, and any that are not are a threat to breastfeeding rates. I would have though that the opposite was true. Apart for a very few lucky people, breastfeeding is not a wholly positive experience. It can be a fabulous, intimate, powerful thing. It can be easy and convenient. It can also be painful, tiring, restrictive and utterly utterly boring. I think we do women a terrible disservice is we don't admit that. I'm sure that sense of disappointment is what stops some women feeding when they hit a problem - that all the propaganda depicts it as natural and normal, with little mention of the difficulties and also the way it can drain your sense of self. Being told repeatedly that it is best for your baby does not help when at 6 months you are still marooned on a sofa for hours a day trapped under a hungry baby while your toddler wails for attention. Acknowledging that it is a different experience for everyone (and for many people, something you just get through because you know you are doing good) would help, surely? So let all those of us with different experiences have our own view, including Charlotte Church.
(FWIW I breastfed both my kids exclusively for 5 months, then my first until the age of 15 months and my second until 11 months. But I don't feel the need to tell people that I enjoyed every minute of it when it isn't true).
