There we go. We know darling has had a good feed ending 0130hrs but she was crying and refused to sleep.
After drifting in and out of sleep for 4 times, under my constant instruction, rather than cajoling, darling finally fell into deep sleep and awoke to feed again at 0430hrs.
We even tried waking her up at 0400hrs to feed but she was soundly asleep, waking up only half an hour later.
She definitely understands speech tones and energy transfers.
