Placenta- barrier between the mother and child; receives nutrients, passes out waste, etc. Umbilical cord – attaches the embryo/fetus to placenta Episiotomy – surgical cut in area to prevent tearing.

MOTHER’S DEVELOPMENT

FIRST TRIMESTER: 1-3 MONTHS Tender Breasts Nausea Weight increase

SECOND TRIMESTER: 4-6 MONTHS Looks pregnant Heart rate increases Energy increases

THIRD TRIMESTER: 7-9 MONTHS Skin stretches over abdomen Slight contractions felt Pressure on bladder Fatigue, back pain, heart burn, and breathlessness

ONSET OF LABOR

1 ST STAGE Head of fetus drops lower, easing pressure on mother’s lungs and abdomen Mucus plug expelled Uterine contractions stronger and more regular Sac ruptures and fluid leaks out Cervix begins to dilate (.5 in./hr) to 10 cm or 4in.

2 ND STAGE Begins after full dilation of cervix Mother feels strong urge to push Baby emerges from the birth canal

3 RD STAGE After the baby has been delivered, cutting the umbilical cord separates the baby from the placenta. When the placenta has separated from the wall of the uterus, it is eased out of the vaginal opening.

PROBLEMS DURING AND AFTER PREGNANCY

DURING Fetal Alcohol Syndrome (FAS) – a set of defects that affect a fetus that has been exposed to alcohol during pregnancy. Gestational diabetes – diabetes during pregnancy.

FETAL ALCOHOL SYNDROME

BREECH BIRTH Frank breech - the baby's bottom comes first, and his or her legs are flexed at the hip and extended at the knees (with feet near the ears) % of breech babies are in the frank breech position. Complete breech - the baby's hips and knees are flexed so that the baby is sitting cross-legged, with feet beside the bottom. Footling breech - one or both feet come first, with the bottom at a higher position. This is rare at term but relatively common with premature fetuses. Kneeling breech - the baby is in a kneeling position, with one or both legs extended at the hips and flexed at the knees. This is extremely rare.

AFTER Postpartum depression – depression that occurs after birth that can result from physical changes, emotional factors, and lifestyle influences.
