Pip - I have just gone back to work and still BF DD. She has never taken a bottle (or dummy ) but will drink from a sippy cup. The Heinz basics 4m+ one was fine to begin with. That is how she has EBM now. I have gone back on x2 8h 12-2030hrs shifts per week and soon x3. For me that is the FT number of days I do (normally 12 hour shifts) but I will stay reduced hours for a while yet. I express once through the shift and often combine my 2 breaks together so I can express and still get to eat. You are entitled to breaks for expressing. Check your HR policy.

It isn't too bad - DD punishes me when I get home and the nipple is never far from her for the next 24 hours but we are still fully BF and will continue to be so until she self weans. The introduction of solids helps and, often, they will hang out waiting for you to come home to feed
