breastfeeding past 6 months

I am still breastfeeding Nate and yes he is over 6 months old and no I don't plan on stopping quite yet. I am returning to work in June though and by then I would like to have stopped breastfeeding during the day to avoid the pumping at work scenario; but I enjoy nursing and plan on continuing at night and first thing in the morning for as long as Nate and I want. 

The other mommies in my weekly group have all already stopped nursing their children and many have asked when I will put Nate on formula. I don't quite know how to answer their question.

I never thought I would be the last one in the group nursing. I don't consider myself to a hardcore "attachment parent", though I do agree with (and loosely follow) many of Attachment Parenting's core principles. And I certainly don't think I will still be nursing Nate into his late toddler years, though it's hard for me to know how I will feel when that time comes. 

All I do know is that after a difficult start to breastfeeding where I had to pump every 2 hours around the clock while Nate was in Special Care, and had to use shields until he was 2 months old, I am enjoying nursing now.  I don't want to stop just as I have really gotten the hang of it. And also, if I do stop, how will I be able to enjoy after-nursing sleep cuddles snuggled on the sofa like this?
