Abstract
Background: Future neuronal development of the child is affected by the sleep characteristics during the infancy period. Proper development of sleep during early years of life is linked to mental and motor development. Hence, assessment of sleep during infancy is an opportunity to study the impact of sleep on the maturation of brain.

Aim and Objective: The aim of the study is to estimate the development of sleep spindle characteristics and K-complex in sleep EEG in normal healthy infants, that is, from 2 weeks to 12 months of age.

Materials and Methods: Our sample consisted of 50 healthy vaginally delivered full-term infants (27 boys and 23 girls) of both sexes with five repeated EEG assessments at 3-month intervals from 2 weeks to 12 months of age.

Result: The K-complexes were absent up to 3 months started appearing after the age of 3 months. Sleep spindles were absent up to 2 weeks of age gradually established at 1 year of age in healthy full-term infants.

Conclusion: The healthy full-term infants exhibited normal sleep spindles and K-complex development on EEG. Sleep EEG characteristics may be used as predictor for mental and motor development later in life.

Key words: EEG and Sleep Spindles; Sleep EEG Infant; K-complex on EEG
