Hi all first post so here goes

I have an iphone 6 I previosly had an iphone 5s  all was fine until I gave my daughter my iphone 5s as I no longer needed it, she put her sim in the phone, buy as soon as she did my phone the iphone 6 turned into my daughters phone all my contacts dissapeared all my daughters contacts appeared on my phone and the wallpaper changed from the picture I had to a completely different one of a wave, 

So how can this have happened? please help

You need to set up your daughter with her own apple id.
At the moment both phones are syncing to iCloud under the same account so the latest changes will sync back to both phones.

Hello Sarah, and welcome.
Did your daughter have an iPhone prior to you giving her your 5s?
It appears her details have overridden yours?
Hopefully you have previously backed up to iTunes or icloud?
As MI5 suggests you'll have to restart each device and set them up with your individual icloud accounts.
