Brian Owens with twin daughters Ellie and Olivia, 3 months
"When the girls were very little, Olivia got her leg stuck in her crib during the night and woke up screaming. I bolted out of bed and frantically broke the crib rails, injuring my shoulder. Thankfully, she was fine. But it was at that moment that I realized I never wanted anything to hurt them and I would do whatever it took to keep them safe and happy."

Brian West with daughter Charlotte, 6 months
"The first night we were alone with Charlotte, she wouldn't stop crying. We tried everything to calm her down. Finally I started softly singing one of my favorite songs -- 'Eight Days a Week,' by The Beatles -- and she instantly stopped. She just looked at me as if she had known me for years. I'll never forget it."

Shaun Osting with son Gabriel, 3 weeks
