“Love feels the same, as deep and true as it ever did. We may be oceans apart, but our love for each other and our daddy transcends it all.

“In these very real moments, I am gracefully reminded of what it’s all about. Love and human connection is all we ever really have and I am very grateful for the love and connection I have with these four remarkable people, my family. ❤️’
