sky blue eyes forever?

Both Aiden and Sky were born with slate blue eyes but right around eight months Aiden's eyes changed to hazel. Sky's eyes on the other hand have lightened over the past two months.
I'm wondering if this means she'll keep her blue eyes. I've heard that a baby's eye color can change in the first year. I'm keeping my fingers crossed for blue eyes. How appropriate would it be for a girl named Sky to have blue eyes?!

Now that you've seen a close up of her eyes at two months, please take my poll and tell me what color eyes you think Sky will end up with.
