Few Questions
What is your category FSW, PNP, CEC ?
What is your AOR date ?
Is this paper based application or online through Express entry ?
What about Background Check status?
This is my take on your file
Assuming your AOR is 5th Jan 2016 & your file was on hold due to Wife medical and Child birth, on 5th Aug you submitted the remaining Medical, so technically you submitted the entire file on 5th Aug.
If Medical is not completed they do not process the file further but In your case you are PA and your docs were complete so you can expect a decision (PPR) on your file within next 60 days
Thanks
