Hello,I have a 5 week old and was just after some advice really.She is currently having 4-5oz of formula every 3 hours which I am sometimes having to wake her up for.Should I be leaving her longer than 3 hours if she's sleeping? Also people have been saying that she should be staying awake after her bottles for up to 2 hours before I let her sleep again so she doesn't spend all day asleep and sleeps at night.She barely even manages an hour after her bottle awake.Is it possible to have any sort of routine this early on? Thanks
