All study-related visits, with the exception of the first sampling of mothers at gestational week 28 at the maternity clinics, will take place at the Sunderby Hospital. Midwives at the maternity ward will be responsible for all sampling at the birth timepoint and assist with collection of samples from the neonates at 48h. For all other time points post-48h the same clinical team, consisting of two specialized neonatal nurses, will meet all participating families. The same paediatric allergy specialist will examine all infants at 12 months and 48 months of age to diagnose any allergy and/or allergen sensitisation. At 48 months, the children will also undergo an assessment of neuropsychological development, motor skills assessment, (?) anthropometric measurements as well as an oral health examination.
