I tell DD I love her all the time - whenever she goes down for a nap, gets up, has a cuddle, is playing, is breathing!! DH and I tell each other we love each other all the time too. I don't think you can ever say it enough, and I don't think saying it all the time lessens its meaning. DH and I both know how much we are loved by the other through actions, but its still nice to hear and I want my daughter to grow up feeling the same way. I've lost too many people unexpectedly in my life to not take every opportunity I can to tell those I love how much they mean to me. When my former fiance died a few years ago it meant a lot to me that the last words we said to each other were "I love you".
