How do I stop photos from my phone going to my daughters ?

Sounds like you are sharing a common AppleID.

This is a really bad practice; your photo issues are just the tip of the iceberg.

Implement family sharing, Set them up each with their own AppleID, and implement parental controls.

Don't Share One Account:

She is likely seeing this in the Photos app, as photos uploaded to your iCloud library. So, I'd say have her set up her own Apple ID. If you want to see it, then you could perform Family Sharing. And, if applicable, then you might want to set this up as a child's device. You'd set this up anew, as if you were to sell it.

Thank you for the photo.

Resections:

What you should do is use Parental Controls. You would set up restrictions. See here:
