Brief summary
Physiological processes leading to a preterm infant to be able to feed orally has not been fully understood. The investigators hypothesized that maturation of autonomic nervous system may play a major role in this process and kangaroo care may accelerate this maturation. The investigators will use heart rate variability to measure the maturation of autonomic nervous system.
Interventions
Kangaroo care is a technique practiced on newborn, usually preterm, infants wherein the infant is held, skin-to-skin, with an adult.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| HRV-Sympathetic-Short Measurement-LF | 5 Minutes | By using Holter monitorization for 24 haur. LF (frequency domain, low frequency measurement): The low-frequency (LF) spectra represents predominantly sympathetic with some parasympathetic influence in the 0.04-to-0.15 Hz range. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time Domain Measurements of HRV | 5 Minutes | By using Holter monitorization for 24 haur, 5 different measurements get by 5 minutes heart rate analysis: SDNN, SDANN,SDNN index,Rmssd,pNN50 SDNN: ms, Standard deviation of all NN intervals. SDANN: ms Standard deviation of the averages of NN intervals in all 5 min segments of the entire recording. SDNN index: ms, mean of the standard deviations of all NN intervals for all 5 min segments of the entire recording RMSSD: ms, The square root of the mean of the sum of the squares of diVerences between adjacent NN intervals. pNN50: % NN50 count divided by the total number of all NN intervals |
