mixed race babies

for the first few weeks carey was really pale skined and his hair was so blonde, over the last few months hes gone from being really pale to quite dark, as i spend every minutue of the day with him i havent really noticed it happening but i saw somebody yesterday who hasnt seen him since he was a couple of weeks old and she said he looked like a completely different baby and looking back at photo's and things he does.

im not really asking a qestion here but im just curious to know if anybody has/knows of any mixed race babies whos skin colour changed so dramatically so quickly.

Thanks
