hi there, my daughter has this, although slightly different. she has bronchea trachea laringo malysa (please excuse my spelling!) which basically means the whole way up, not just some of the windpipe. hers was very bad and we ended up in PICU when she was 5 months old, but they seem to think this was caused by having so much trauma to her throat (whole different post, she had had 6 intubations by that stage, and open heart surgery the week before her airway collapsed!). she came very close to needing a trachy for a while, but luckily we avoided it by some time in PICU and a CPAP mask. she is 20 months old now, and it is soooo much better. she is on night oxygen still, but again all her other health issues have compromised her airways along the way, and it is a very slow recovery process. they initally said to us that it would resolve itself as she put on weight, she weighed 4.2kgs at 7 months old, and it has. she is only really noisy if she's really tired or has been playing a lot or had physio. she had a camera down there last month and they said she has more space in there than they have ever seen with her. but a recent sleep study showed her windpipe does still collapse on itself when she is in a deep deep sleep hence the need for oxygen still, but they are amazed at how good she has come. the drs have told me she is pretty much worst case senario for BTL malaysa, and just about the only case as bad as hers that hasn't required a trachy, so i imagine your bubba should be just fine and grow out of it. I am here if you have any more questions. HTH, Louise
