NO WORRY MR. PRASATH. AS LONG AS BOTH YOU AND YOUR WIFE HAVE VALID RP IN QATAR (WIFE SHOULD BE UNDER YOUR SPONSORSHIP) YOUR BABY WILL HAVE 2 YEARS RP WHICH FIRST YEAR FREE AND FOR SECOND YEAR YOU WILL HAVE TO PAY ONLY QR. 400.

PLS NOTE THAT IMMIGRATION DEPT WILL ISSUE/STAMP UR BABY RP FOR 2 YEARS( FIRST ISSUE) AFTER 2 YEAR U CAN RENEW IT FOR 3 OR 5 YEARS.

HOPE MY ANSWER FOR YOUR QUESTION.
