I have been breastfeeding for 10 weeks now and iv never expressed neither in my other babies either but I'm more busy now and would like to express so I can get a little more help most of the time it will be me breastfeeding but if i have a back up bottle of mums milk it will be helpful, but I bought a manual pump and only managed 1 Ounce in 20mins...how can I improve this as it feels like a waste of time.
