If you're still breastfeeding an older baby....

...how many times a day do they feed? My 17 month old eats loads of solid, sleeps all night without a feed (and attends nursery 3 days a week where he goes all day without boob quite happily) and ideally I would only do a breastfeed morning and evening, but if I am with him he demands it constantly and I mean constantly. If I did "don't offer don't refuse" he would never be off the boob. I don't want to stop completely but him constantly whinging for it is driving me insane.

It's you he wants. He associates feeding with being close to you and getting attention. So the answer might be replace feeds with other cosy close moments. So sitting on the sofa with a special cuddly object next to you whilst reading a book, a story tape a special toy you only look at next to him. So mummy time without the milk. Or milk in a cup with a teat even. But a bridge from breastfeeding. I breastfed until just under two years but I found he was quite active so only a bit of sitting around occurred, and then slowly changed from breastfeeds to just cuddles on sofa. Last feed was morning feed, night time bedtime feed was dropped second last.
Also have you considered he is keeping your supply going by these frequent feeds and it's what nature intended him to do if there are these big gaps? It's probably hardwired into human toddlers.

Especially if he has been ill since October -maybe he really does need a lot of extra cuddles and sucking for comfort.
