Yes, applicants should provide birth certificates, according to the UK Visas & Immigration supporting documents guide:
Under 18s β we strongly recommend you submit the following information otherwise it may delay consideration of your application.
- a Birth Certificate or legal document (such as adoption papers) showing the relationship between you and your parent or guardian
However, unless asked, you should not need to include your marriage certificate as, within your application, you'll identify her as your partner with whom you'll travel, as well as other identifying information.
