Adult + 2 kids born abroad approval waiting time

Hi everyone,

I am and 2 my children are EU citizens with Settled status granted more than 1 year ago. Children were born abroad before moving to the UK.

According to naturalisation timeline people get approvals in approximately 2 month time. I'm wondering if any of the following make approval waiting time longer. Maybe someone had similar experience.

1. Applying together with children
2. Having excess of 190 days spent abroad due to illness during pandemic (have uploaded docs from hospital)
3. Having Russian as a second nationality

How children receive their naturalisation certificates if applied together with adult? During ceremony or earlier by post. If the least then does it mean they can't travel before they get their passports? because I still will be able to as my ceremony can be weeks later after approval.

Many thanks

UKVI Nationality applications processing target is six months, though many receive their approvals faster than, sometimes longer than that. Children's certficates are normally handed to the parents at their ceremony, otherwise they are posted .
