I am breastfeeding my baby now 8 days old she started off very hungry as my milk took a few extra days to kick in so was feeding round the clock to stimulate, when my milk kicked in she slept for a whole day and night and I was having to wake her every 4 hours to feed and she wasn't really very interested , as if she was full . however last night she did the opposite and I was constantly feeding from 8pm until 3am every time I took her away from my breast she cried and wud wake up crying and frantically suckling on anything that went near her at 3 am i then handed her to dp to give her some expressed milk which she drank all of and still cried and suckled for more milk so dp gave her (with my consent ) 40ml of formula which again she drunk and was still asking for more then I continued to bf her until 5am when she finally dropped off until 7am when she woke for another feed and then every hour all day
