Bindi went on to thank everyone for their warm messages and noted how special it was to celebrate her first birthday as a mom.

"My first birthday as a mama has been the most beautiful gift," she captioned a few photos with Grace. "Our sweet Grace Warrior's face says it all. Today I celebrated by feeding Monty the crocodile and hugging my gorgeous girl (not at the same time!). 💛 Thank you for the lovely birthday messages and kind support, it means the world to me."

Last month, the new mom opened up to PEOPLE about how life has been since welcoming Grace on March 25.

"When we first got her home, it's as if she's always been with us," she said. "It's a really strange feeling when you can't remember what your life was like before this beautiful little person. I never knew love like this before."
