I would definitely get dh involved now - then if weaning the feed is really hard, dh can do BT without you (and your boobs...). We gave dd about 4 oz of milk in a sippy cup and yes, I did warm it up. We went cold turkey as well. She was ready, so I think that's why it worked so well with us - and dh was there too, so she began associating BT more with the stories/prayers/songs than bfing. good luck!!
