Generally curious

So my baby daddy was born with super blonde hair like platinum blonde but as he got older it changed to medium brown. I was born with blonde hair which most people will say mousy blonde and I stayed blonde up until I dyed it brown when I was 12 but I'm now blonde again. He's also got bright blue eyes whereas I've got green eyes. So I was wondering if anyone could give me a rough idea of what my baby's hair and eye colour could possibly be?

I find out the gender in January.

Edit: both our mums were born blonde and both our dads were born with black hair. Neither of us have any ginger in our family's.

His sister was born blonde, one of my sisters was born blonde whereas the other was born brunette.

He has a very small family as his mum was an only child and his dad has 1 brother(10 people, 1 sister, two nans, 5 cousins, 1 aunt and 1 uncle)whereas I have a very big family. Most of my family are blonde with blue eyes and the same with his.
