I am trying to express some milk to store in the freezer in case I get sick or I need to sleep and hubby can bottle feed the EBM, but I am struggling.

I have an Avent manual pump and I often struggle to get even 20mL, 10mL is sometimes a pipe dream. On a very good day I'll get maybe 40mL. This is pumping for a good half an hour.

What am I doing wrong? It is SO time consuming and I find I have to sit awkwardly to get the milk to flow down the neck of the pump which has left me with an aching back.

I hate having to wash and sterilise the stupid pump every time I use it just for 10mL, it's doing my head in. Please help.
