Hope you are okay, Tarz. I know exactly where you are coming from. I too had enough at 12/13 months but I just couldn't seem to let go. My little boy who is 20 nearly 21 months only has it to go to sleep, occassionally he may fall asleep himself whilst sitting on my lap and having a cuddle (has to be really tired though) or if I am holding him and I am rocking (which happened today). I still have the occassional feeds at night which I think is more comfort because he doesn't have a dummy, never has. He knows that he really only gets it around lunch time and then bed time. I don't know what to do about her pulling at your top. I found keeping him busy seemed to distract him from the breast or offering food and going out in the mornings and being home around lunchtime for his nap also worked. Doesn't seem to want it anymore when we are out, too much else going on.
Will she take the bottle at night? Not sure if you could try that instead, a formula bottle may fill her up, not sure. I couldn't get him to take a bottle either.
It does get easier as they get that little bit older. The hard part for me will be stopping it all together, if that ever happens.
Not sure if I have helped at all. Good Luck and keep your chin up.
