FLR(M) Extension - Help!

[McGregor03]

Hi guys, sorry if it has been awhile since the last time I posted something in this forum as I've been busy with my 2 yr.old son and work.

I am applying for thr extension of my spousal visa soon and am a bit of confused in few parts of the form.
First is the financial requirement I need to tick;
7.2 WHAT IS THE FINANCIAL REQUIREMENT YOU ARE REQUIRED TO MEET.
- Applying with no child (an income before tax of at least £18,600 a
year
- Applying with one child (an income before tax of at least £22,400
A year
* The thing is am the only one who's applying and I and my husband have a 2 year old son who's a british citizen and he's born here in the UK. BUT WHICH ONE IS THE RIGHT ONE TO TICK? The £18,600 or £22,400?

The second one is,
7.6 ARE YOU/YOUR SPONSOR RECEIVING ANY PUBLIC FUNDS?
-Yes or no? And if so how much do u receive each mon?

* I think it's a yes coz my son who's a british citizen has an allowance which belongs to CHILD BENEFIT but it goes to my husbands acc.
and on the bottom there's CHILD BENEFIT THAT HAS BEEN MENTIONED AND YOU HAVE TO PUT THE AMOUNT THAT YOU RECEIVE? Do I need to put something in mine or just on my sponsor? As he's the one who's receiving the benefit not me.

I hope someone could help me. Any help would do!
