Hello My baby is 22 days old . I breast feed her. When I feed her she falls asleep in 10min. Then even if I try to wake her up by tickling her feet or ear, she doesn’t wake up. If I try to wake her up by changing her diaper or by swaddling her, she take a little feed and then doesn’t fall asleep soon. She stays up for 1-2 hours and sometimes becomes very fussy, keeps crying all the time. When I feed her less than 10min, she wakes up within an hour to take another feed. If I feed her for 15-20min she sleeps for good 2-2 and half hours. If that much feeding enough for her?
