My little girl is 7 weeks old she will sleep for up to 9 hours at night with feeds inbetween but will stay awake all day if i let her, it feels like i have a full time job and its getting her to go to sleep. I have heard i shouldn't let her cry for longer than a few minutes but this means i have to nurse her for and hour or more so she can sleep for 10-20 minutes and then shes awake and this cycle goes on all day. Can anyone help me.
