4-Year-Old's Reaction To Learning She'll Be A Big Sister Is Adorable (Video)

Kayla is, according to her mother, "baby mad."

After the 4-year-old swooned over everyone else's babies for months, mommy blogger Kellie finally shared the news that Kayla will soon have a newborn sibling sharing the house with her and her brother.

Kayla couldn't believe her ears and immediately began crying joyful tears, which Kellie says lasted a solid 10 minutes.

If Kayla's already crying this much over a mere baby announcement, imagine how she'll react to an actual baby.

Hint: There will be tears.
