Baby Passport still in process

Hi everyone, I have searched everywhere but no luck. If anyone can help.

I have applied British passport for my son, who was born in Pakistan.

From the past 6 month, I have sent all the necessary documents to HM Passport Office to assist them with the process and recently had my Skype interview for the Passport for my son.

I also need to inform yourselves that, I came to Pakistan to bring my wife to the UK who has been granted a residential visa on my behalf and she’s supposed to utilize the visa and travel. I have already extended my wife's visa multiple times which is valid until 4th October 2021. I'm afraid I won't be able to extend it anymore. We are hoping to travel within this time limit.

Unfortunately we cannot travel until the Passport of my son arrive and I do not know for the fact that how long this passport issuance is going to take.

Please advice
Thanks in advance
