Fastest MN1 application method

Hi all,

I'm applying in person for mine and my wife's ILR on the 27th Nov - we expect to get the ILR back in about 10 days after that (mid-December).

We have a 9 month old baby daughter born in the UK and we're planning on applying for her British citizenship straight after - ideally in time to get her a Brit passport before travelling abroad in February.

I've been reading about different MN1 application routes.
As it's a tight schedule, I was wondering if anyone can recommend the fastest method - or at least the one was lowest risk of delays?

Any help would be really appreciated.

Thanks in advance!

There isnt a faster or quick route. Some take a few weeks and others take a few months.
