yes
Child support is intended for the child's benefit, not the mother's.
Yes, as long as she is under the age limit for child support you are still liable, even if hs has children of her own.
It depends on the state you live in and the age of the child.
Depending on the state, yes. See link
If the child is providing more than 50% of his or her own financial support, then no, child support would not continue. However, if 50% or more of his or her financial support is still coming from the custodial parent, then child support would continue like normal.

You may not be able to. If your children where under the age of 18 when the decree for support was created then the non-custodial parent is still responsible for that support. Only a few states back date, which means that if you had the decree written up when the child was 17 then the non-custodial parent would have to pay from the day that they left the house. States can garnish wages for back child support, and also garnish tax refunds to pay child support. If it was dropped due to the child moving out on their own at age 16, which is when a child can rent their own place in Texas, than it cannot be reengaged.
If you're in the US... Pregnancy/giving birth does not emancipate a minor, so yes, you are still responsible for child support (but only for her, not for her child of course--the responsibility for child support for her child belongs to that child's father).
Yes, that doesn't relieve you of your duty to your child pregnant or not.
Yes, the child is still considered a minor, even though she has a child of her own. You will owe child support until she reaches the age of majority and has graduated from high school.
If you are living own your own, you are not a child. If you are 18, you are not a child. If you are still in high school, you show good character. Don't give up, you will know the pride and feel the power of what you do know for your whole life.
The courts will mostly likely consider a child who enters the military as "emancipated," and, therefore, terminate child support. But don't stop paying on your own!
