Question

What do i do if i have lost my child passport now need a adult passport?

Answer 1

You need to apply for your adult passport if you are going to be traveling.  Here is a site (below) which will put you on the right track for that.  

Good point, the child passport needs to be reported missing if you really can't find it, and you have the link for that from another writer.

Answer 2

You need to report it as lost or stolen:
