Hi Judy, I did not read your first post on this topic so I don't know if
this is relevant, but I do know that larynx structure and movement
certainly can have an impact on an infant's ability to breastfeed.
Do a Lactnet search for Laryngomalacia (and it's cousin,
Tracheomalacia). Laryngomalacia is a "floppy" larynx, meaning that it
collapses with each breath taken. The babies have loud, gurgly breath
sounds, sounding much like a coffee percolator. The condition may make the
work of breathing take more effort, so the infant might fatigue sooner, or
might seem sweaty during breastfeeding. They might have more difficulty
protecting their airway at feeding, aspiration. Upright positioning may
help. Most babies with this Laryngomalacia outgrow it within 6-12 months,
and in general it is not a serious condition.
Tracheomalacia is a similar situation involving the trachea, but is
typically more serious and has a bigger effect on breathing effort and may
require surgery where they put rings in (to mimic the rings of cartilage
that are not firm enough) to stabilize the tracheal walls.
HTH. Don't know about a hiccup connection, if that was the initial
question, but at least this info might be interesting to a "newbie". :)
Ah! I found your original post... so. Hmm. I'd bet the laryngo improves by
six months, and six months is when your quote states the larynx "descends"
more. My bet is that because it's cartilage, just like many other parts of
the newborn that are "looser" earlier on (ears, hip joints sometimes, etc)
the cartilage firms up and maybe that's why the larynx settles- when the
cartilage rings harden. The hormone Relaxin at work at birth, and wearing
off shortly later?
