Photos included one of Annie as a little girl with a vast collection of assorted hair clips and bows in her hair, as well as a photo of her as a toddler in Amy's arms.

The day before Annie's birthday, Amy shared another celebratory post on social media in honour of Mother's Day.
The TV star is incredibly close to her mother Joanie, and posted a gorgeous snapshot of the pair drinking wine on the beach at sunset, alongside a sweet message.
She wrote: "My mama, she loves fiercely, she protects passionately and she gives selflessly... I am who I am because of HER!

Last week, meanwhile, Amy received the all-clear after going for her twice-yearly cancer check-up.
The TV star battled breast cancer in 2013 and has since gone and got tested twice a year.

After receiving the positive results, the ABC star posted an uplifting message online, alongside some photos of her celebrating with her friends.
She wrote: "It's days like these - when your friends rally to support you - that I truly understand what life is all about - love, friendship, connection.
"Surviving is one thing, thriving is another and twice a year when I get my testing done its a humbling day, a reset button, another pinch to remember why we are here and that all we have is right now #friendship #love #cancerthriver."
