My mother once told me- something like an old saying- that a child will be like whoever you least want it to. Whoever you dislike the most in your family, you will find in your child. So if there is someone in your family you don't like- watch out! cos the child might inherit their looks or personality. In cases where they try to keep the daddy a secret, the baby will more often than not, look just like the daddy.
