Almost 50% of all children have at least 1 episode of noisy breathing before the age of 2 years and almost 25% of these children have more episodes of noisy breathing. The lack of an objective technique for diagnosing noisy breathing children often leads to overrated diagnosis of "wheezing", whereas there may be other noisy breathing phenotypes, like "rattling", that don't favor from the same therapeutic treatment. Presumably, different underlying pathophysiological mechanisms are involved with different biomarker profiles characteristic for different phenotypes. The goal of this study is to optimize the diagnosis of noisy breathing infants and toddlers. Children will be followed for a treatment period of 6 weeks and will visit the paediatrician 3 times (week 0, 3 and 6). During the consultations breath sound analysis will be performed and a breath sample and a nasal mucus will be collected to analyse biomarker profiles. Both methods for diagnosing noisy breathing infants are non-invasive and will be compared to the standard procedure of the paediatrician which consists of auscultation and palpation of the chest. An objective and non-invasive method for diagnosing noisy breathing infants and toddler will pave the way for more cost-effective and personalized prescription of therapies which will increase the quality of life of children with noisy breathing.

RECRUITINGNoisy breathing diagnosis made by pediatrician based on anamnesis and auscultation
Noisy breathing diagnosis is made by the same pediatrician and is based on intensity and duration of both wheeze and rattle are scored on a scale of 0 to 10, whit 0 indicating not present and 10 indicating very high intensity or of continuous duration.

Treatment response assessed by online journal for parents
Parents are asked what type of noisy breathing symptoms their child had during the day. Options are: (1) Wheezing; (2) Rattling; (3) Both, but mostly wheezing; (4) Both, but mostly rattling; (5) Both in equal amounts, (6) No noisy breathing today. In the online questionnaire sound fragments of wheezing and rattling are available incase parents are in doubt.
