I have been BF DD2 since birth. She is now 6 months and I am considering expressing so that I can leave her with her dad etc. Do I need to sterilise at this age? I have bought some bottles but am also wondering if I should go straight to a sippy cup (or do you think a bottle would be more comforting. Do you freeze your milk in the little bags or just use containers (do they need to be sterilised?) I guess I am reluctant to go out and buy a heap of equipment because I am not sure if I will be very committed when it comes to expressing. Would love to hear your thoughts and about your experiences.
