okay, we pretty much ran thru the options for
@Ami *******
and then some :O
1 - apply for an unable to travel due to covid extension (as you're from the UK they don't issue the letter) so just go to your immgiration office and apply
2 - apply for an unable to travel due to medical reasons (as you just had a baby, get a letter from a doct or hospital) and just go to the immigration office and apply.
That's pretty much your choices.
