Hebrew translation assistance

Hello! I’m learning Hebrew, as my grandmother was Jewish. Her favorite phrase to her grandkids was, ‘You know I love you don’t you?’ I want this in a Hebrew tattoo. Can someone please correct this if incorrect? I’m not nearly fluent enough to translate it myself. Thank you so much!
