piglet, of course, I think it's brilliant that this kind of thing is being discussed and it's great to hear other opinions. I'm glad this isn't turning into a bunfight -yet--.
There is nothing wrong at all with not wanting to breastfeed an older child. Every family has different values, different goals, different ideas. But there is no evidence that breastfeeding an older child is wrong, or unnatural, and there are always benefits to breastfeeding until the child wants to wean.
From the point of view of a mother that is breastfeeding a 3.7yo, there are benefits for me for sure- lower risk of several types of cancer and osteoporosis for a start, and it means I can eat a fair bit and still fit in my skinny jeans
but there are also lots of benefits for my DD.
I admit that some days I wish she would just wean already but that's just part of the process. She's growing up and one day she won't need it, but I'm happy to carry on until then. Breastfeeding an older child is very, very different to breastfeeding a baby so it's not really about wanting to baby them at all.
Just thought you might like to hear the perspective of someone on 'the other side' rather than just being given scientific research :) Maybe I won't change your mind but it might help you see it from a different angle.
