Hi Liv,
I've created a concept with three hearts in it. One larger one to symbolize you, two smaller ones to symbolize your twin boys. In some versions, the two smaller hearts are baby blue; others, they are the same color as the larger heart (you). The pattern of the smaller hearts is an "emoting" or "radiating" pattern. Also symbolizing the act of giving and sending love. Love is coming out of the larger heart, almost floating up toward the sky...the universe, via the web, if you will.
If you have any questions, let me know. Have a great weekend! -Jennifer
