You've done so well to get to this point :) I'd imagine you haver some of that bitter sweet 'my baby is growing up, I'm loving discovering who they are becoming but I do miss them being small' feeling.
I wonder if you are annoyed at your DH though, and if that's why you posted? I would be extremely annoyed if my DH tried to force an end to breastfeeding with a bribe without my prior agreement.
If you and your son are ready to stop then that's fine, it just stuck me that it seemed to be taken out of your hands and I wondered if that was affecting how you were feeling about stopping.
My DS is only 5.5months and I don't know how long we'll feed for, but I'd want it to be DS's decision, or mine and I'd have stern words for any one who said he was too old (starting with asking the rude individual what age they were when they stopped drinking cow's milk). I would be upset at my DH undermining breastfeeding in front of DS or trying to get him to stop. As a parent, he could talk to me about it if he was concerned about the feeding for some reason, but not in front of DS, and I'd be furious if he tried to manipulate him into stopping before either of us were ready.
Your DS may well be ready since he hasn't resisted it, so it's totally up to you if you want to take advantage of the lack of feeding and to carry on and refuse if he asks. I'm just saying I could understand if you were annoyed at your DH for initiating the stop in the way he did and felt you'd been cheated out of making the last feed special (though I'm sure it was).
As none of the other posters have reacted this way, and as you didn't say it, maybe I'm barking up the wrong tree and thinking too much about how I'd feel if it was DS.
