Travelling with a baby to UK - dual citizen

Hey all,

So both parents are British and the little baby is born in NZ. We booked travel to the UK before we found out about the new changes (I know...). We did, however, get baby an ETA because it was before they changed those rules at the start of the year.

I have seen lots of people mention that airlines won't know if you are dual or not & the UK can't turn away a citizen.

My baby has to be carried by one of the parents through immigration & so it's going to be pretty clear that bub is a dual citizen right?

We can make other plans as the passport won't arrive in time, we are just wishing we could do our original plan to visit grandparents for the first time
