Other mums horrified I am still breastfeeding 18 month old ds

[Knackeredmother]

just returned from a rare night out for a friends birthday. Lots of other mums there. Some with babies around 4-6 month old some with older and grown up children. Got onto the subject of feeding and mentioned I am still breast feeding 18 month old ds.
They were horrified. Got comments such as'its wrong' ' he's got teeth now' 'it's just for your comfort not his'.
Now I wouldn't dream of commenting on how they feed their child and was a bit taken aback. I am an educated woman and could normally come back with a rational argument but the 2 glasses of champagne put paid to all rational thought!
Has anyone else encountered this? out of at least 10 mums I was the only one who had breastfed for more than 2 weeks and felt a bit crap about it all.
I wonder if the best thing is to not ever mention it in future but on the other hand think why should I?

Can i add my support and say how saddened I am at some people's need to assert their opinions on others, it's just awful.

I "still" bf 23m DS, I work full time so it's normally just morning and night, but some weekends he'd go back to nursing like a newborn if he could get away with it - monkey! Anyway I wanted to add that I have had 2 x 5day/4night business trips away when he was around 16-17m ..... so, although not ideal, perfectly possible...

Don't worry. My 2 yo still gets a nighttime bottle and I get the same response. As always: women can be their own worst enemies. It's your choice and if you are both ok with it (dare I say happy mom&child) then sod the rest.
