Hi
Please update your profile so that we can see at least some basic info about you.
For passport renewal , usually one can update/renew the passport withing the last one year. your kid passport exprires in nov 2014 so you can apply for the same on or after nov 2013. there is still provision if you say you want to renew your kid passport
due to photo visibility issue (something like that) then passport office consider your application and may issue another passport at this point of time. once you get it then update to your lcoal vo about the new passport of your kid,send old and new passport copy.here old means copy of first and last page having cancelled stamp on it.
now,if you dont apply for the passport at all.
cic has condition related to passport expriry and that i guess six months. most of country is having six month criateria.
if your passport is valid for less than six month then they will ask you for renewal and then release visa on it.
considering the above situation, you are haivng time till may 2014,if you get visa with your family by that time then no issue.but if they demand passport after may 2014 then you MUST have to submit updated passport.
I would suggest you to wait till november 2013, if you will get medical by that time then send then current passport of your kid. if you wont get medical in nov 2013 then update passport and send updated details to your lcoal vo.
all the best. and if you need more info please send me PM because sometimes i am not checking all pages![/b
