If I have read it right, then your 9 year old will have been born after '98 when the rules changed and therefore needs her own passport
Your 13 year old, if she is already on it, can still travel on yours. Quote "Before October 1998 many children were included on adult passports. If your child is on your passport they can continue to travel with you in this way until"
If you need to renew your passport then your children cannot be included even if theyre were previously. Quote "If you renew or change your passport in any way your child can no longer be included on it and you should apply for a first 5-year child passport for them if they are under 16"
