LO is now five weeks, can I start to express now? She is feeding every 2 and half to three hours and going for upto 4 and half hours at night. I just thought that I could start to freeze milk and 'think' about trying her with an expressed bottle. My only worry is that she will absolutely refuse to have a dummy and makes faces as if I have put something truly disgusting in her mouth, so will she take to a teat? My son was brilliant, at four month I went back to work and combinations fed him until eight months when my milk dried up, but this time I want to continue with breast milk and express feeds when I go back to work.
