What do we do pls?

[temmyt]

Hi all I have been reading lots but not found a situation like mine. I have an Ilr and my partner of over 2 years has 5 year retention of rights having been divorced from an eu partner. Our boy was born in my home country and I left him with my mum. We want to bring him over now and according to what I read both parents must have settled status. I will be the sponsor but under what category should I apply because my partner does not have Ilr? Do we still qualify to use vaf4 or what? We are not married yet and how does that affect my application for our boy. Pleaseeeee advise is needed urgently
