My 3 week old is awake most nights either from 10-5am or if I'm lucky 2am-5am. I am breast feeding and during this time awake she just wants to be nursed. During the dat she will sleep happily no matter what noise there is-I did the hoovering yesterday with her in the baby bjorn and she slept throughout. I try and keep night time quiet and dark and day time noisy and bright, andhave tried the no cry sleep suggestions with no change so far. During the day she wakes up evey 3 hrs for a feed and is alert for only an hour or so appart for feeding. Any suggestions on how to go from here?? Also is it ok to sleep during the day when she sleeps or is that going to make her even more nocternal. She is fully breast fed and at her last weigh in she had out on 7 onz in a week.
