Just wondering if anyone knows about travelling with children on different passports? Most of my family are Australian-British and have passports for both countries but I recently gave birth to a baby in Australia and will be applying for an Australian passport for her. Can I travel in and out of the UK with my baby if I use my British passport and she uses her Australian one? I have a feeling this may be prohibited due to the risk of parents leaving countries illegally when a child custody case may be pending...? There is no child custody battle in my situation, thankfully!
