My mom had two kids - me and my younger brother, both of us were overdue and my mom had horrible labors with many complications. We were both almost 8lbs
I've had four kids. 3 of my kids were born early - one at 38 weeks, two at 39 weeks. My other baby was overdue. I was induced with 3 of my kids (not the one born at 38 weeks). My two boys were both in the 6lb range while my daughters were 7 & 8 lbs. My labors were mostly uncomplicated and I recovered fairly quickly, which is the opposite of my mom's experiences.
There was one similarity between myself and my grandmother, though. When she had my mom (her second), she was in labor days before she went into active labor. With my youngest, I was in early labor for almost 6 days before going into active labor.
