all of the sudden pump not working

post #1 of 7
Thread Starter 
I have a new Medela pump in style. I work 3 days a week and also pump once at night to boost supply and because babe doesn't nurse much at night so I get really full. I have been pumping 4 oz off a breast. Last three nights, I have milk but can only get two oz off a full breast.

I bought new pump parts today, but no change. Usually, babe wakes to eat, I feed him from one breast then pump both, getting 4-5 off the non used breast and 2 off the used one. Now its 2 off the non-used breast and 1/2 off of the non-used one. I have have more milk (can feel it) but all of the sudden can't pump it. Worry when I go back to work on Wednesday and have to pump the 14 oz he drinks in 3-4 pumping sessions.

Any ideas?

How old is your DS? It could be your supply is regulating. Also, when you're not nursing full time, you will be able to pump a lot more.

For me, the pump never gets out all the milk as effectively as a baby does, so I get that same "there's more in there!" feeling that you describe. Sometimes, if you have the time, you can keep pumping after the milk stops flowing and until you get a second let-down. That still doesn't get it all, but it does help and should also stimulate your supply, if needed.

I assume you replaced membranes when you say pump parts??

Does the suction seem good? Check your tubing for leaks, make sure all parts are fitted well, and double check that the membranes are laying totally flat.

Sometimes I find a breast massage of the "full" areas helps get more milk out. Obviously having a handsfree is necessary in order to do that, but it might be worth a try.

Finally, see if the milk is fore milk only, or a mix. Just leave it in the fridge for a couple days, and let the fat separate. Foremilk will have very little fat, but hind milk will produce a nice, thick layer. If it is a mix, it is just your supply regulating. If it is fore milk only, then you might have a pump problem. Good luck!

are you using the right size flanges? that makes a HUGE difference.

Call Medela. When my PIS died they overnighted me a new one. It made a huge difference and I'm still using it. They also do good trouble shooting over the phone.

do you still have the manual? the front face plate pops off of the pis-- if it gets loose, it can affect suction. All you might need to do is pop it off, and pop it back on again.
