Hi Keith, so relieved to hear you have a clear diagnosis, and the surgery is done already...in some ways, it would have been easier for us if dd's had been treated surgically so early on. She probably didn't need it as much as your ds, but two years down the line whilst removing tonsils etc they did exactly the same thing - cut away two tiny bands of cartilage either side of her trachea (windpipe). Its great that the stridor is less already!
I would second Mad4's advice re investing in a humidifier/purifier - we mostly use the humidifier bit, as dd doesn't really have allergies. It helps anyway when they have croup, or a cold, or stuffy nose - so worth having, and doubly so with laryngomalacia. I do'nt know how much the surgery makes a difference, but maybe you won't have to live with very much at all....? Just be a bit more vigilant with infections, ie go to GP sooner and tell them about the condition and the surgery; try putting him down on his side rather than on his back (wedged); raise head end of cot for a while after surgery, longer if needs be for the reflux. If the reflux meds are not sufficient (dd had domperidone as well, some LOs need stronger meds) ask for them to be changed - he may be unsettled after feeds till he's about 3 months old anyway, even with meds, but lots of screaming/arching or throwing up will let you know if the reflux is bad.
When weaning, we found dd managed best with finger foods, so she could be in control - we had a shaky start, but she got it very fast and did well. Other LOs prefer softer foods to start with, but dd didn't - she liked 'edges' from the beginning.
Later on, if you find he's struggling with sleep and/or eating, ask the ENT team to check his tonsils....we were ocnfused by the largyno for a while and didn't realize dd's worsening sleep apnoea (when they gasp and can't breathe during sleep) was largley down to tonsils meeting in the middle!
And don't worry about squeaky noises, if they don't seem to be bothering your ds - its normal, and he'll grow out of it
Anything you want to ask as you go along, do - and if you ever want to CAT me, feel free.
