Are your babies eyes still blue?!

Melissa • My husband and I were blessed on November 19 2015 with our son Nolan! Currently pregnant with baby #2 👨‍👩‍👧‍👦
My son is almost 6 months and his eyes are still as blue as can be. I heard that if they didn't change by around 6 months that means they are staying is this true? My hubby has blue eyes so I'm really hoping they stay! 
He's 11months now and they're stil as blue as can be lol love them!
