Getting a UK passport for 7 year old and New Born.

Hi,

I am going to be so bold as to start a new topic on the subject even though it is covered here http://www.thaivisa.com/forum/topic/694440-getting-a-uk-passport-for-my-newborn-half-thai-child/

I have found that some of the info in the previous post is dated, so i want to make sure i get all the up to date information of the topic.

I want to apply for a UK passport for my 7 year old and my new born. I am sure there are some differences in the application process with regards to a new born and child of a few years??

Any and all info is much appreciated.

Thank you
