Pump no good?

I didn’t use that first pump but found the Mendela manual one didn’t work for me! There’s so many different factors that can contribute! How much your baby has fed, how long between them breast feeding and you pumping, how much water you’ve drunk etc.

Also pump wise do you have the right size cap thing on?

I pumped not exclusively but for first few months every day and some days I would get loads and some hardly anything. On the hardly anything days I would pump little and often and also pumped one while my daughter fed from the other.

One week I also had literally no supply when pumping but my daughter wasn’t grumpy so assuming it was okay when she fed herself then by the next week it was back to normal pumping🤷🏼‍♀️

Could also try hand expressing?

Try pumping overnight or first thing in the morning, your supply will be at its highest then. I’d also only pump 20 mins per breast, 40 mins just won’t be practical if you try do that every day (20 mins should be long enough to get some milk) You may also find you need to drink a lot more, I am exclusively BF and couldn’t believe how much water I have to drink to maintain a good supply. Hope this helps a little x
