I'm separated with my wife, and we have a baby thats about a year old. I love him as much as humanly possible, but I have a concern... I heard a rumor that my wife may or may not have cheated on me around the time that the baby was conceived. The baby has some traits that neither myself or my wife have, but shares a resemblance to the man that was rumored to have been with her. Is it possible, or even legal to have a maternity test done without her knowledge? I'm sure there's nothing to worry about, but I'd prefer to know for certain.
