Toddlers red hair turning blondisg white?!?

Not sure if I'm seeing things. Since he was born he has had light red hair but a very light blonde in a certain lighting. Recently I've noticed his longer hair is turning a very light blonde almost white?!?

Anyone else go through this with a red head? Seems really early to change colors?? I'm kinda sad I loved the red head. He has brunette parents and a brunette twin but somehow that little red head Gene from our Scottish-irish roots poked through with him lol
