Lol I tried 4 different cups (including 1 with a straw) and my daughter still wanted nothing to do with drinking milk from them! I stopped "really trying" at 14 months. At 15 months she was READY (key word for my daughter...she's a little stubborn :)}. I found this "tumbler" cupby playtex, it is a stage 4 but it looks like a travel coffee mug, (which looks like mommy's cup) and she took right to it. She drinks her milk out of that with no complaints. She just turned 16 months and only has one bottle before bed. I figure she will let me know when she is done with the bottle. If you really want your little one off the bottle now, my friend had her son throw all his bottles away. She said he did it with out a fight and never asked for it again. (He was a few months older than your child though). Another suggestion would be to pack up the bottles (with your child's help) and give them to a baby who needs them. (if you know any other babies). I hope some of this helps! Good Luck & let me know how it goes.
