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.

RECRUITINGHRV-Sympathetic-Short Measurement-LF
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.
Time frame: 5 Minutes
Time Domain Measurements of HRV
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
Time frame: 5 Minutes
