Birthdays are just birthdays, right? They're just giving a nod to the passage of time... WRONG. Birthdays are an emotional rollercoaster when you've got kids.

To this day, I can't get through a rendition of Happy Birthday on the daughter's special day without bawling. Your kids' birthdays just mean and represent so much more. Their little lives flash past you and the showreel gets longer every year. Hence why I'm bawling posting Chris Hemsworth and wife Elsa Pataky's touching instagram marking their twins' second birthday. 

Pataky captioned it: "Happy birthday my little boys, there's nothing that makes me happier in life, than being a mum and watch you growing up everyday! #mum #boysbirthday #bestlove #party #already2 #loveyou"
