In a fanfic where they have a baby, their relationship would shift. They would now be partners not only in crime - solving but also in parenting.

But through it all, their love for each other and for their baby only grows stronger.
The kidnapper could be an estranged family member of Beckett. There might be some family feud or inheritance issue that leads them to believe that by kidnapping the baby, they can gain an upper hand.
