My mom was two weeks overdue with me and had a fairly normal uncomplicated labor, however, she was just over 4 weeks overdue with my sister. The complications were horrendous. My sister was born with the cord wrapped around her neck, very little amniotic fluid left and she was being suffocated by the placenta, she was born completely blue. The doctors had a hard time getting her heart started and when they finally did they told my mom that if she survived, she'd likely be severely handicapped. They didn't allow my mother to even see my sister for two days after she was born because the doctors were convinced she would die. When they finally did let my mom see her, they kept stressing that she would not be 'a normal child'...
Thank God she turned out perfectly, no lasting problems or anything and is now a very healthy young woman who is the mommy to two precious children of her own, however, it was very clear that the problems occurred because my mom had been allowed to go over the 42 week mark.
Compared to going through this, my mom would tell you any day that if she could do it over again, she would have been induced and my sister would have been born two weeks earlier.
