Looking to apply for my infant daughter (5 weeks old), and had a few questions. Hoping that we can do the interview when we are in YYZ, probably late July or August (we live in CVG now). Wife, I and toddler all have Nexus already. (note: Mods - if you think this should belong in Nexus info. thread, please feel free to move there).

Questions are:

• Is the 20 business day processing time (so I guess, more like a month) fairly accurate? - I ask because when wife and I did our renewals last year, I believe it was at 50-60 days (and i think my wife's, for some reason, took even longer).
• Anyone know if an infant would likely be faster, or slower then the general population (ask since i could see reasons why being an infant, and not necessarily having info. in the background check systems at all, etc. could mean a shorter or longer approval process).
• I've already completed [most] of the application online, and it seems to accept birth certificate (which obviously doesn't have a photo) as both a citizenship and entry document. Her passport is processing, and will probably arrive early July, so if we want to add that to the application, we'd need to wait until then to actually submit it. Anyone know if there is a disadvantage to simply applying with a birth certificate, and then just providing the passport at the interview? Could this make the processing time longer? Or is it best to wait to be able to provide it in the application?

Appreciate any insight into this.
