00:02
Are you ready to talk
about newborn nutrition?
Well, I'm ready.
00:05
And you're here.
00:06
So let's do it.
00:08
So there are several options
for feeding the baby.
00:11
We can do breastfeeding.
00:13
Naturally, I want to take a minute and
just talk about the word breastfeeding.
00:16
So breastfeeding is sort
of our historical term,
how we talk about feeding
the baby with our breast.
00:21
But I want you to recognize that not
everyone uses the word breastfeeding,
because they don't
call these breasts,
they might say nursing,
or they may say chest feeding.
00:30
So make sure that you talk to your client
about what term they would prefer to use.
00:35
The other option, of
course, is bottle feeding.
00:37
And I'm going to say this a
several times during this lecture,
recognize a bottle
feeding is an option.
00:42
I'm going to tell you all about
the benefits of breastfeeding.
00:45
But recognize there is a choice
and parents have the right to do
whichever they choose to do.
00:52
So let's first start off by
talking about breastfeeding.
00:55
So I'm using
breastfeeding globally.
00:57
Remember, nursing,
chest feeding also works here.
01:01
So recommendations for breastfeeding
from the American Academy of Pediatrics.
01:05
This is the organization that provides
recommendations for pediatric care
is that there's exclusive breastfeeding
for the first 6 months of life.
01:13
And then after that,
that we will use complementary feeding
along with breastfeeding
for the rest of that year.
01:21
Okay, first 6 months,
breastfeeding only,
6 months to a year,
complimentary feedings,
so they get to eat table foods and
baby foods and things like that.
01:31
But we'll continue
breastfeeding.
01:34
Now let's look at the recommendations
from the World Health Organization.
01:38
They give recommendations
for the entire world.
01:41
They also recommend exclusive breastfeeding
for the first 6 months of life.
01:46
However, after that,
they recommend continue breastfeeding
along with complementary
foods for the first two years,
that's much longer
than one year,
which is what we recommend
here in the United States.
02:00
Why do you think that is?
Well, because we know
it's good for the baby.
02:03
And in some countries, there's a lack of
really quality foods and things like that.
02:08
So getting breast milk actually
helps to sustain the baby
much longer than
past that first year.
02:16
Let's break down the
physiology of how we make milk.
02:20
So the pituitary gland
actually releases prolactin.
02:24
Prolactin is a hormone.
02:26
Guess what it does?
The word gives it away.
02:29
Prolactin.
02:32
Pro like I make
it, I encourage it.
02:35
Lactin like lactose, like milk.
02:39
Prolactin.
02:40
So the pituitary gland
is responsible for that.
02:43
We also have alveoli that are
actually responding to the prolactin
by increasing milk production.
02:49
So the pituitary gland
releases prolactin,
and the alveoli respond to that
by increasing milk production.
02:57
So how do we get the release of
prolactin in the first place?
Well, the suckling of the baby.
03:02
So every time the baby
goes to eat at the breast,
that suckling
stimulates prolactin.
03:08
Now here's the really interesting
fact is that the suckling
actually stimulates the
milk for the next feeding.
03:14
So it's not an instant process.
03:16
And that's why we get into sort
of a supply and demand process,
we've got a suckle at the breast
to get ready for the next feeding.
03:24
The other hormone we need
to talk about is oxytocin.
03:28
Oxytocin is responsible for
the let-down of the milk.
03:32
So remember,
prolactin makes milk.
03:36
Oxytocin in this case is
responsible for the let-down reflex.
03:40
Now, maybe you remember oxytocin
from our lecture on labor
because oxytocin stimulates
uterine contractions,
but it also stimulates
the let-down of the milk.
03:52
So what does the oxytocin do?
It actually causes the muscles
around the areola to compress.
03:58
And that compression actually allows
the milk ducts to evacuate the milk.
04:03
So one more time,
prolactin responsible
for making the milk
and oxytocin is responsible
for getting it out.
04:12
You got it.
04:14
I don't know if you remember.
04:16
But way back in our lecture on
physiologic changes of pregnancy,
I talked about the
stages of lactogenesis,
and I promised you that
it would come up again.
04:25
Well, here it is today.
04:26
We're going to break down stage ll,
lll and lV of lactogenesis right now.
04:31
So I have a graph here and I want
to make sure it's clear to you.
04:35
So you see on the left
side on the vertical axis,
we're going to look at the
stages of lactogenesis,
and then on the horizontal axis, we'll
look at when it occurs in pregnancies.
04:44
So we'll put those together and talk
about what happens at each stage.
04:48
So stage l happens early in
pregnancy around 16 weeks,
and at this point, we have the beginning
of the production of colostrum.
04:57
So remember,
colostrum is that liquid gold.
04:59
We're going to talk more
about that in just a minute.
05:02
Then when we get to stage ll,
we get to secretory activation.
05:07
So this is when the
mature milk comes in.
05:10
So this is around day 4 and it
goes all the way up to day 10.
05:15
Then at day 10,
we have Galactopoiesis.
05:18
And at this point,
the milk is well established,
the baby is suckling, and we're getting a
good feedback between supply and demand.
05:26
So everything is just
moving along really smooth.
05:29
And then we get to the
end of our lactation,
when we get to the time where
the birthing person says,
"You know what, it's time that
we not breastfeed anymore."
We are in stage lV.
05:40
So this is Involution.
05:42
So our milk supply is going to go
down because we no longer have supply,
no longer have demand.
05:49
Everything slows.
That is stage lV.
05:52
So one more time, stage l of
lactogenesis we are producing colostrum.
05:58
Stage ll is when we get into mature
milk, it starts to be produced.
06:03
Stage lll is when we're enjoying a good
feedback between supply and demand.
06:07
And stage lV is when we
get a decrease supply
because we're going to
end the breastfeeding
or nursing or chest feeding.
06:15
Remember,
lose terminology there.
