A lot! I have 3 small children and I make sure I tell them how much I love them every chance I get. Now if you asked them, they will tell you that I say it way too much, but if you asked my husband, he will tell you that I don't say it enough. I also tell my friends and family how much I love them all the time.
I started doing that when I was 19 and my best friend lost her mother. That day I knew that there was no guarantee of a tomorrow. I do not want to die wondering if the people I love knew I loved them so here I go, letting them know :)
