[Psychosocial components of illness in the child].

In 77 children aged 1 year the mother-child interaction in relation to the morbidity of the child was analysed. The following factors appeared to be correlated to the quality and quantity of the mother-child interaction: (i) the date of the first acute illness, (ii) the frequency of illness during the first year of life, (iii) the duration, frequency and seriousness of the illnesses after admission to day care at the age of one year. Conclusions are drawn for the practice of infant care.
