Well I realized Kate didn't nurse at all today and I don't think she did yesterday either.

She sat on my lap and asked a couple times today, but when I asked her if she was thirsty and did she want some milk she nodded and eagerly took her sippy cup. So I think at this point that's still just how she tells me she's thirsty!
I'm not pushing the issue, if she is upset and really wants to nurse then I'll let her, but I have no milk and it's really starting to hurt my nipples!
But yeah. Kinda crazy that she's pretty much done, 18 months later! She'd still be nursing if I hadn't gotten pregnant and lost my milk supply, but she's clearly not devastated about it. I'll get upset if I think about it too much, I'm intentionally not saying I'm weaning her, just that I'm "not nursing her right now."

Makes it easier for me to cope with emotionally.
