My ds2 has blue eyes, which surprised us a lot because both his father and I have brown eyes!

Ds1 has really dark brown eyes too. Dh's parents both have brown/hazel eyes too, so there is quite a recessive gene in there somewhere (despite all jokes about the postman!)

Ds2 has really light bright blue eyes, not that deep cloudy baby-blue, and they didn't really change, although I think they got even lighter as he grew. He is 20 months now so I hope we are safe, because I so associate him with blue eyes now that I would be devastated if they changed now!!
