Thanks for your patience.
You are not affected by the recent rule changes and you will be able to apply for Indefinite Leave to Remain a month before your visa expires provided that you have observed the conditions of your visa and are still in a married relationship with your spouse. Confirmation here- http://www.ukba.homeoffice.gov.uk/visas-immigration/partners-families/citizens-settled/spouse-cp/settlement/
Similarly your children that have come here with your will also be able to apply for ILR at the same time you do, please see confirmation here on the final paragraph under the heading “Children under 18):- http://www.ukba.homeoffice.gov.uk/visas-immigration/partners-families/citizens-settled/spouse-cp/children/
However, you can only name them in your application for ILR (so that they also get ILR) if they are under 18 at the time of the application. With respect to your other child who is already over 18 (and any other that are over 18 at the time you make the application) they will have to make their own appliaction because once you are over 18 you are no longer regarded as a child dependent but as an independent adult .
Therefore she will have to make her own application using her own application form.
