Minor- proof of citizenship child 4 months old

[J2018]

Hello,
How long does it for proof of citizenship for a 4 months old child to be processed and approved?
How long is the waiting time once the application sent from the embassy to case processing center in Canada? When to get AOR? How long is the mailing time. Please elaborate more.
Thanks
