There is nothing wrong with breastfeeding longer term - I only fed mine for a year, but I get the impression lots of women feed a lot longer and just don’t talk about it. It’s quite hard to get a baby off the breast, they just love it. So I can easily see some children want to carry on when they’re 4,5.
However there is a particular type of woman who seems obsessed with childbirth and breastfeeding, often stretching out the brief obsession you have when your own are tiny for many years after their children have grown up- frequently these women train as breastfeeding councillors or hypnobirthing trainers, or something centred around that birth experience. They’ll often enthusiastically longer term feed.
These are the women who you’ll see arguing on mumsnet about weaning and virgin gut theory even though their children are teenagers.
And that is exactly the type of woman who would go to the daily mirror to do a story on breastfeeding her children in the playground
Whilst I’m really grateful that these women use their obsessions to do things like train as a BF counsellor, the other end of the stick is that I do think they can cause anxiety to new mums with the ie hysterical weaning debates
