In the same manner as heartwarming picture books like bestsellers Let Me Hold You Longer and Love You Forever, I Couldn't Love You More expresses a sweet, loving, yet powerful message: I couldn't love you more, but there is Someone who does. Beautiful illustrations with adorable animals are paired with the song lyrics to give parents the perfect backdrop for tender interaction and sweet snuggle time. Matt was the lead singer for Sanctus Real, a Grammy-nominated Christian Rock band, for 20 years. When Matt and his wife, Sarah, were halfway through their pregnancy, they discovered their son would be born with Hypoplastic Left Heart Syndrome (HLHS), a rare congenital defect. Matt and Sarah's son, Bowen, was born on 9/9/10 and has built a large following through the Hammitt's Blog (Bowensheart.com), K-LOVE, and ABC news. A portion of the proceeds from the book goes to the foundation the Hammitts started to help parents with children who have this heart condition. Bowen continues to beat the odds as he recently celebrated his 10th birthday. A documentary on Bowen's life released in February 2021, and he was even surprised on his birthday by the Good Morning America team, who wanted to celebrate with him through a Zoom call.
