Is there any way to unlock my phone without deleting it all I have a lot of pictures of my kids on it

No, but you might have been making backups of your phone, correct? So you could use a recent backup to restore the phone after it has been reset and set up again. The phone will look just like it did when the backup was made.

If you were not making backups of the phone, we'll save the lecture, but hopefully you will incorporate this in the future.
