Pretty much every movie with a baby in it probably has a scene like this
one: baby is born and gets smacked into the world. No wonder the baby
starts out screaming. The fact that Plath chooses a stereotypical image
of first-moment baby-ness suggests that she's not going to be claiming
that her baby is extra-special in any particular way. Nope. It's just a
baby. A very loud baby.

Once again, Plath resorts to fairly typical images of babies to describe
her newborn. This time, though, the image gets turned on its head just a
little bit – this newborn is, in fact, a statue, which is something
slightly less dependent and helpless than other forms of babies.
All night your moth-breath Flickers (10-11)
It's funny how one little baby can command so much attention, huh? But
our speaker has moved from thinking about the ways that the baby
interacts with her life to – well, letting that baby play a part in her
life. Even though the baby is no longer screaming, our speaker is paying
all sorts of attention to it!
Your mouth opens clean as a cat's. (15)
There's something lovely and pure in this description of "you," the
baby. Cats are well known for not recognizing anything else in the world
but themselves – sort of like babies. But at least this image is
"clean" and peaceful. Maybe our speaker is coming around to her baby.
