My ds2 had his 2.5y check today where as part of the discussion I said that he nurses on demand, which is usually before sleep and when waking up. This resulted in a lecture on how he no longer 'needs' breastfeeding and it has no nutritional value. I was also told not to nurse him when putting him to bed and that he 'must' be awake when he's put to bed. She then proceeded to say that I wouldn't want him to be calling me when he's 32 to be nursed to sleep 
I found her manner so condescending and not interested in hearing anything I might want to say so I just smiled and nodded 
When my son had his last check at 11m I was then also told (by a different HV) that he should not be nursing more than 2-3 per day. that time as well I just sat there like a lemon and said nothing 
However, I did want to check what the official line from NHS is re duration of breastfeeding. I'm aware what WHO says but on NHS I could only find the 6m min ebf recommendation.
I'm probably too much of a coward to send any feedback to the HV office but it would be good to hear others' views and I'd be grateful for links on any NHS info
