Reapplying will not make the process faster. I assume you are a lawful permanent resident. While a petition for the child of an LPR typically receives a visa faster, he/she must wait for his/her priority date to become current in order to immigrate. It appears your son's priority date is not current based upon the email you received from the NVC. There is no way to bypass the wait for a visa to be available.
