My dd2 has laryngomalacia, it was diagnosed when she was 4 weeks old and in hospital with RSV bronchiolitis. In itself, it never caused any problems - though she did have reflux, and was on meds from 8 weeks till about 18 months for it.
In conjunction with RSV, and being 4 weeks old, it did cause problems - kids with larygnomalacia are more likely to be hospitalized when they have upper airway infections, simply because their airways can be narrower. Not necessarily a problem, but can add to other ones iyswim. She also had big tonsils and adenoids, by the time she was 2, and the floppy larynx didn't exactly help - though again, it really wasn't the main problem. She's now had tonsils and adenoids out, and the ENT consultant did minor surgery cutting two tiny bands of cartilage either side of her windpipe to allow her larynx to expand more easily - said he 'might as well, since they were in there already', and I agreed.
She still gets the classic 'squeak' when she is asleep and has a cold, but otherwise its irrelevent now and she's a blooming 2.3
Re weaning, we had no problems at all once we let her choose her own foods and feed herself: she hated purees from the start, and I suspect it was harder for her to swallow than 'bits' either because of her tonsils, or her larynx, or both.
Its great that your LO hasn't reflux symptoms thus far - apparently, 80% of kids with laryngomalacia do.
dd has never turned blue, or choked on anything, though we did worry about her breathing whenever she had a heavy cold or chesty cough: the RSV episode taught us to be that bit more vigilant with her than with dd1.
There was a flurry of laryngo/tracheomalacia threads a few weeks ago - someone started one for info and support for all concerned with it? I wish I could do links...but if you run a search, in the Childrens Health section, I'm sure you'll find it
