Values are means ± SEM. P-values calculated by Wilcoxon's signed-rank test.
N-FS, non-feeding session; FS, feeding session TST, total sleep time; WASO, wake after sleep onset; NOA, number of awakenings; AAL, average awakening length; MI, movement index; FI, fragmentation index; SEM, standard error of mean.
