My baby is 3 months 11 days old. She started to sleep 7 to 8 hours in one streach at night without feeding from few days. If i try to wake up and feed she will not wake up and if force fully do, she won't take feed properly. She will wake up by her own and cry for feeding. My concern is shall I leave her and make her to wake up by own. is it ok to sleep for long hours without feeding. please answer
