Need to wean toddler ASAP!! help!!

[Neenee Jellybeanie]

She seems to prefer just gripping my nipple (OW!) to actual feeding. If it were up to her she would sit on my lap holding on all hours of the day and night. So right now I'm trying to break that habit by only letting her suck; if she just holds onto the boobie, it goes away. This works well enough for the most part as she feeds for shorter periods than she death-grips me, but of course I want her to leave 'em alone completely! She still holds on when she goes to bed though. It's too difficult to get her to sleep when she's upset over not having boobs so I tend to try to convince her but she gets her way in the end anyway.

edit: just saw your post jungle mum. I offered her a bottle with dairy milk, since she's seen DD2 have EBM but she didn't really drink it. Perhaps the milk flow is too slow for her. At the same time I don't really want to get her onto a bottle at this age. I try to offer her other drinks including chocolate milk, sometimes it works and sometimes it doesn't unfortunately. I've also tried telling her boobs are for babies etc. but she argues with me, "No! My have a boobie!"
