hi .we have a baby born in the us .now the kid live in Haiti with my ex's mother .I send money every month for the baby.can she give me child support?

I don't understand the question.  You send money every month for the child, but you're asking if you can get child support.  If there are other children involved, then you might be able to get support for those children, but I don't know how a court is going to enforce support for a child not living in the US.
