Thanks for the reply.....I think I typed my situation too quickly, my head is about to burst LOL!
I know now that the child visa 101 comes with a date of entry just like the other migration visa's so I would need to apply for this close as possible to when we know when we will make the official move to Australia. i.e 14 months before.
I need to know what happens if me, my husband and child go to activate our PR via 190 visa, but we now have a new born, who was born after medicals and 190 visa was granted....would I simply be able to take the new born on a vistor visa with a return ticket (we would all have return tickets as this would just be activation), then apply for their child visa at a later date when we returned to the Uk.
I hope that makes sense
