The Story of Piper and "Nigh-Nigh"

When Piper was born, this author and illustrator, Piper's Grammie, knitted her a baby blanket. As Piper got bigger, she named her blanket "Nigh-Nigh". She played with Nigh-Nigh and napped with Nigh-Nigh. She took Nigh-Nigh wherever she went. One day, Piper couldn't find Nigh-Nigh. She looked everywhere but .....no Nigh-Nigh! Where did Nigh-Nigh go?
