MN1 refrees and documents list

Hi All,
I and my wife have got ILR granted recently and going to submit the MN1 application for our 2 year old son who was born in UK while I was on Tier-1(G).
I'll be applying by post and not NCS.
I got following questions:

1. For professional reference, I have got it signed from my VAT registered company's Director (as GP refused to sign as refree). 'How you know the child' was filled as 'family friend'. Is the refree profession n relation mentioned fine?
2. For other referee, I'll have our family friend with British passport (he got 1 year ago), sign the application. I'll write relation again as 'family friend'. Is that fine?

Following are the documents I am planning to submit by POST
- Completed MN1 forms (one per child)
- BRP's (me + wife)
- Passports (me + wife),
- Child's passport,
- Child's UK birth certificate/s (showing ILR parent's names),
- Child photgraphs
- Parent's Marriage certificate
- Fee form (separate doc from UKBA site)

Do you think anything needs to be added?
I dont think I need to attach my expired passport.


Thanks in advance.

Any suggestions please?

Referees should be fine.

Documents list is fine (although one parent documents is enough. Marriage certificate not required if child born after 2006).

Can anyone please suggest - how many photographs are needed for the kid? there is only section where you can attach 1 photo. Do we need to submit more than that?

Could you please let me know how long the whole process will take as i am also goin to apply for my child. thanks
