Brief Summary:
The aim of the intervention is to examine the effect of a combination of the two bacterial strains BB-12 and LGG, provided for 6 month, on the prevalence of infections and allergic manifestations in small children, and how a combination of BB-12 and LGG affects the immune system, gastrointestinal tract and the microbiota. Children are enrolled during 2 winter seasons.

Primary Outcome Measures :
  1. Number of days absent from daycare due to respiratory and gastrointestinal infections [ Time Frame: up to 6 month ]
    Recorded weekly by the parents using web-based questionnaires


Secondary Outcome Measures :
  1. Acute upper respiratory tract infections [ Time Frame: Up to 6 month ]

    Number of days with acute upper respiratory tract infections (URTI); Number of children with at least 1 episode of URTI; Number of children with at least 3 episodes of URTI; Number of URTI episodes/child/year; Duration of URTI episodes (days);

    Additionally,symptoms of cold (defined as 2 days with runny/stuffy nose or cough)

    Recorded by the parents daily/weekly using web-based questionnaires.


  2. Acute lower respiratory infections [ Time Frame: Up to 6 month ]

    Number of children with at least 1 episode of a lower respiratory tract infection (LRTI).

    LRTI include bronchitis and pneumonia

    Recorded by the parents weekly using web-based questionnaires.


  3. Gastrointestinal infections [ Time Frame: Up to 6 month ]

    Number of children with at least 1 episode of diarrhea; Duration of episodes with diarrhea(days); Number of episodes/child/year with diarrhea; Number of days with vomiting.

    Recorded by the parents daily using web-based questionnaires


  4. Fever [ Time Frame: Up to 6 month ]

    Number of days with fever

    Recorded by the parents using web-based questionnaires


  5. Antibiotic use [ Time Frame: Up to 6 month ]

    Number of treatments with antibiotics during the intervention period

    Recorded weekly by the parents using web-based questionnaires


  6. Allergies [ Time Frame: Up to 6 month ]

    Number of children developing allergies during the intervention period (asthma, allergic rhinitis, atopic dermatitis, food allergies); Age for diagnosis of allergies; Use of medication due to allergies.

    Recorded by the parents using web-based questionnaires


  7. Absence from day care due to illness other than infections [ Time Frame: Up to 6 month ]

    Number of days the child is absent from day care due to illness, which is not due to infections.

    Recorded by the parents weekly using web-based questionnaires


  8. Parental absence from work due to illness of the child [ Time Frame: Up to 6 month ]

    Number of days a parent is absent from work due to illness of the child (infections and other illnesses, respectively)

    Recorded by the parents weekly using web-based questionnaires


  9. Medical visits [ Time Frame: Up to 6 month ]

    Number of visits to a doctor due to infections and other illnesses, respectively.

    Recorded by the parents using web-based questionnaires


  10. Change from baseline in Thymus size [ Time Frame: At baseline and after 6 mo (end of intervention) ]
    Change in thymic size during intervention period will be evaluated using ultrasound


Other Outcome Measures:
  1. Change from baseline in biological markers for the immune system [ Time Frame: At baseline and after 6 mo ]
    Analysis of biological material investigating the effect on the immune system by biological markers .

  2. Change from baseline in biological markers for gastro-intestinal tract [ Time Frame: At baseline and after 6 mo ]
    Analysis of biological material investigating the effect on the gastrointestinal tract.

  3. Change from baseline in Biological markers of allergy [ Time Frame: At baseline and after 6 mo ]
    analysis of biological samples investigating the effect on allergy by biological markers at baseline and at 6 mo
