My youngest is almost two and I'm still breastfeeding him. I've noticed lately that he's getting more restless at night, so am supplementing him for the first time so he can get what he needs, so I think it won't be long before he is weaned. It's such a comfort to him when he wakes up in the night to have a cuddle and a breastfeed, I'm not in any hurry to stop.
They don't need to be breastfed exclusively after six months or so, but starting solids doesn't mean you have to stop breastfeeding entirely. The World Health Organisation recommends women continue breastfeeding alongside appropriate foods for up to two years and beyond. Of course women don't have to do it for that long, or at all if they don't want to, it's just a recommendation. http://www.who.int/topics/breastfeeding/en/
Unfortunately I didn't get a chance of breastfeeding as much as I wanted to, I wasn;t producing enough milk for whatever reason, and although I was seeing a lactacting nurse I did persist, but I was worried for my baby he wasn't getting enough to feed on so I had to go on formula I wa.s disappointed.
