hi,
is this question because she has blue eyes?
or rather ... are you questioning the colour of her eyes because you have doubts that you are the father? or...
are you questioning the fact that you may not be the father because of the colour of her eyes?
have you spoken to her mother about your doubts? she is the only one who can put your mind at rest (apart from a dna test)
i gave a responce to your question about the eye colour thing so have a few others... i hope you can soon sort out your worries for your daughters sake.....
good luck ... i realy hope it all goes well with you all xx
