I just weaned my 22-month-old last weekend. I got Maggie's Weaning and read it to her a million times (okay, maybe it just felt that way) and we talked about the upcoming weaning (we set a date), and had a party with cupcakes and one last (really long) nursing. Then I put the stuff that you put on kids' thumbs to get them to stop sucking their thumbs on my breasts. When she wanted to nurse at bed time I reminded her that she was all done nursies (what we call breastfeeding) and that now I didn't make milk anymore and it was all yucky. She started to cry so I let her latch on for just a moment and she made a face and I told her, see, you're all done and now it's yucky. She wanted to try the other breast and I had to peel her off before she sucked all the stuff off. I asked her if it was yucky too. She said yes and I gave her a drink and snuggles and reminded her she was "all done nursies" and could pick a new bedtime routine. She had one other upset that lasted about a minute the next night, but has been fine since and didn't even try to nurse when she walked in on me in the shower this morning (which she usually would). I know this is a little different from your situation, but I got lots of these ideas from other posters on Mamapedia and this is what worked for me. Hope things go smoothly when you go back home.
