71
Progesterone
maintains our pregnancy
- suppress FSH and LH

Why does the blood volume increase in pregnancy?
it is a protective mechanism that provides fluid reserve to compensate for blood loss during birth and postpartum

its also important to note that when a pregnant woman is slowly growing more and more, her body typically goes into this form and it alters her center of gravity
belly out, back bent back

87
we always recommend perform, oral personal care
but most importantly to start to do kegel exercise, which is ?

if the baby blood and mom blood are different, what we do usually give them medication wise?

Adaption of pregnancy
1. she accepts the biological fact of pregnant

3. she prepares realistically for the birth and parenting of the child
patern version
1. announcement phase
2. moratorium phase
3. focusing phase
91
if the pregnant woman has other kids, its very common to see kids that are older do what?
regression
( we dont condone this, so just praise when they start to do better behavior )

97
how do we fix supine postural hypotensive syndrome ?
we fix it by laying on the left side
( when we lay on the left side, it allows us to let more vascular oxygen reach our heart and perfuse more oxygen out to the left side )
