She lied on her application twice already this year and now all of a sudden she will change her story because she's desperate to get here. Don't you think the CO is smart enough to figure this out? This is why one should never lie to immigration and this is why it's so difficult for others to obtain visitor visas from high fraud countries such as Pakistan.
You do not need your mother here, you want her here. Big difference. You changed your own story by stating that "all" of your siblings are here in the U.S. to "only one brother" is here. Sounds like you aren't telling the truth, either. FYI the consulate knows exactly how many members of your family are here.
Your mother can apply as many times as she wants, she'll only lose the application fee but there is a zero chance she'll be approved. She has a pregnant daughter and all of her children in the U.S.. Her ties are much stronger to the U.S. than they are to Pakistan.
