Hi, try to check with the MOI, i think you can extend the visa of your baby for a year but once only. coz i have a friend who have the same problem, but that was a year ago, there might have a new rule now. coz before you'll have to pay for the extension, then after the extension you have to bring back ur baby here.

try to call the moi or better visit their offices for the details. hope this will help you.
