My baby girl is 5 weeks today and she is generally feeding at 11pm 1.30, 3/4 pm then around it can be anything from 6/7 or 8. I really do believe that 5 weeks is way too early for any type of routine with food or sleep. The only thing we are doing is to try and get her used to day and night.... I have found with feeding that at times she will bob, kick, fuss if she is very tired and maybe confuses hunger and tiredness.
