if it were me then i would wean the second feed first, first i would see what happens when you don't go to her, could your dh/dp get up and try to settle her, he may have to do shh/pat pu/pd at this time, the key to it will be to stay consistent, do the same thing and go all the way, when i did this for dd at 7/8 months she cried and carried on for two hours the first night we hung in there, the next night was somewhat better, and the next better again, look this is what i done for my much younger baby, i hope you get some responses from mothers who weaned an older baby, remember she will resist as this is what she has come to expect, you need to break the habit, you can do it, i stopped the second feed about 7 days later, all the best to you
