I am hoping to get some advice.

I have an avent isis manual pump. I used it to express with DD and have used it to express with DS back in the early weeks and it all was going fine but the last few times I have tried, I have been unable to get a let down and it is just so disheartening.

I have tried feeding DS on the other side to stimulate a let down, I have tried getting him to get the let down and then taken him off so I can pump that side but that doesn't work as I am not coordinated enough to do both feed him on one side and express on the other. I have tried having a hot shower and then expressing but just can get the milk flowing. I have also tried hand expressing to get things started. Milk comes out but not very much.

I am starting to lose hope of ever being able to express again.

DS is demand fed so I know I have good supply, I just cant express it out. I am back at work in October so need to start building up a stock pile.

Any advice? Can some people simply not express?

ETA: I have also tried taking all the pieces of the pump apart and putting it back together to make sure its working so I don't think it is the pump. Just the user! wall:
