@Kumar123 If the second child does not have a Social Security number then they are not eligible for a stimulus payment.
If the the first child has a SS number, is under the age of 17 and you are claiming them as a dependent on your tax return, they are eligible for the $500 stimulus payment.
The stimulus payment is reduced or phased out depending on your Adjusted Gross Income.
