Hi quenie.
Don't worry it will be allright.

If I were you click on this link
http://www.hmrc.gov.uk/manuals/cbtmanual/cbtm10140.htm

print this and take this with you when you apply so the caseworker will be informed as well. As I can understand that they are in a lot of pressure and surely couldn't put it all in their heads the exclusions.

We, as spouses of a UK, EEA or Swiss nationals are entitled to claim child benefits.

It says there on the technicalities. So I myself is not worried as I know that the child benefits wouldn't pay it into my account if they made a mistake since I've tick in the box that I'm under immigration control. But like I said, being a spouse of a UK, EEA or Swiss national are excluded of the said immigration control.

So chill

I'm pretty sure I will get my ILR by Friday.
