Hi Ann!
My daughter had reflux... that wasn't too bad once the doctors diagnosed it, but she had projectile vomiting before that. She was about a month and a half when they finally diagnosed her. They gave her some mild antacids and some muscle relaxers and she was fine... that only lasted about 5 months... after that she didn't need any meds anymore.
As far as the Laryngomalacia, I was looking that up, and it sounds minor. I would talk more with your family doctor about it. From what I'm reading, it is just a flabby epiglottis... the flap of skin that covers your windpipe when you swallow. It's what causes your baby to sound like he is wheezing. They say it will strengthen over time, and the Laryngomalacia should go away after about a year to 18 months. But your Dr will know if they have any meds to help in the meantime. I have heard of it... but I've never heard anything major about it. As far as it being dangerous or anything. I hope this helps.
Good Luck!
