“10 years ago you arrived, the most beautiful gift of my life, my greatest love. I am soooooo grateful to be your mommy,” she wrote.

Though Milo is Liv’s only child, she and her boyfriend, David Gardner, are currently expecting their first baby together. The ‘That Thing You Do!’ star is reportedly due in February 2015.
