I absolutely did not say it made no difference after six months !
Health-wise, it is always a nutritious food and drink - however long it is given for. I said I thought it would be hard to do research that showed measurable health benefits in the West for kids fed long-term (ie to two and beyond).
But people bf for more than just health reasons anyway.
They do it because they like it - the physical and emotional connection with their children is impossible to measure on a scale, but it is important to them, and they know it is important to their children.
We often do things for our kids which we find challenging and time-consuming (though often, bf an older toddler is neither - it just happens!) . And we choose to continue doing them, because the benefits (as we see them) outweigh the difficulties.
Weaning advice in the UK changed in 2003. Babies all over the world breastfeed with no other foods and drinks to 6 mths. It doesn't have to be an 'endurance' test, seeing how long they will last! Most babies don't need anything else. Yours might be happier with something extra alongside breastfeeding a little sooner - don't sweat it
