Have you checked your passports recently?! You usually need 3-6 months validity on there when you travel. If you plan ahead and use the routine service (which can take up to 10 weeks) you will save a lot of money. Currently a childs renewal is £53.50 done routinely. £126 if done via the fast track! Ive got lots more information over on my blog post at www.thetravelmum.com - i also have it linked in my linktree - there i go into more detail and discuss passport photo requirements / countersigning and more. We also have a post on getting a first child or baby passport.
