Just found out my little sister is pregnant as well and she is guessing she is about 6 weeks or so. Its truly amazing and crazy,because both of us were pregnant at the same time with our older children. My nephew is about three months older then my daughter and now its reversed lol she will be about three months behind me as I am 17 weeks now. Its truly a blessing and so crazy that we are going to go through it together again lol what are the odds?!
