- wonderment and exciting, talkative about birth
- May not feel entirely maternal yet
- Not receptive to teaching
Taking Hold Phase
Day 2-3, often lasts 10 days

- recovered, feeling more competent
- taking charge, involved and eager
Letting Go
Accepting new role, letting go of old self and finding new meaning in life.
- focus on forward movement of family, planning for future
- re-establish relationship with partner

Subinvolution
Failure of uterus to return to nonpregnant state. Most commonly due to retains placental fragments and infection.
After pains
Contractions after birth facilitate uterine involution.
Maintains homeostasis by clampingnoff blood vessels to control bleeding in uterus, and less clotting.

Released from the pituitary to stimulate and coordinate uterine contractions.
Stimulated by cervical stretching and breast feeding.

What are the 3 stages of Lactogenesis?
- Differentiation
- Activation
- Maintenance
(DAM)
Lactogenesis 1 - Differentiation
Occurs mid pregnancy, Prolactin stimulates cells to differentiate. Progesterone inhibits the onset of copious milk secretion.
Colostrum
- 2-20 mls/feed
- lower in fat and sugar than mature milk
- high protein and minerals
- contains IgA
- laxative effect
Decreased in progesterone, estrogen, placental Lactogen
Increased in oxytocin and prolactin
Lactogenesis 2 - Activation
Feedback inhibitor of lactation (FIL)
Small whey protein acts as local negative feedback mechanism to signal sloe or stop milk production and visa versa
Milk Production feedback loop
- Suckling causes hypothalamus to signal anterior pituitary to release prolactin
- Alveoli in breast make milk in response to the release of prolactin
- Oxytocin contracts muscle cells causing “let down”
Inverted nipple
Pinch test = if areola and nipple goes in

What are the 4 stages of labour?
1st stage = onset of uterine activity to complete effecement and dilation (100% and 10cm)
Latent (0-4cm) and Active (4-10cm)
2nd stage = full dilationto birth of fetus (pushing stage)
- Birth of fetus to birth of placenta
