- Things are full speed ahead
inside your still-flat tummy.
It's only been five weeks since conception
but your embryo is ten
thousand times bigger now
than when it arrived in your uterus.
Of course, it's still pretty small,
around a quarter of an inch
or the size of a blueberry.
Happily, that reptilian
tail has all but vanished
by now and your little cutie is starting
to look a little cuter,
with dark spots that'll become eyes
to holes that will turn into nostrils,
the beginnings of lips
and, believe it or not,
the early beginnings of tooth buds.
But it's the brain that's
getting all the attention now.
Baby's noggin wins the prize
for biggest growth spurt this week
as that busy brain cell factory
cranks out 100 cells per minute.
Your little sprout is
sprouting in other places, too.
The limb buds are elongating
and will soon become defined shoulders,
arms, legs and knees,
gearing up to kick you
within another month or two.
The little paddles at the ends
are becoming more distinct
and will soon develop
into ten kissable fingers
and ten kissable toes.
Baby's liver is in the
early stages of formation
and will soon begin
producing red blood cells.
And hot off the production line
are baby's permanent kidneys
that are standing by,
ready to produce pee
in the next few weeks.
No need for diapers just yet, though,
the embryo's urine flow will become part
of the amniotic fluid it ingests
and excretes continuously
over the next seven months.
