If the two children are your biological children, your child support will be calculated for both. When using our child support calculator at www.rosen.com, indicate the number of children and fill in monthly gross income for you and your spouse, work related-childcare expenses (if any), and health insurance premiums paid for the children. That should give you an idea of what you can expect to pay in child support.
Regarding your question about third-party contributions (spouse’s aunt and uncle), a judge will not consider such contributions unless you request a deviation from the guidelines.
