I ordered a breast pump size 21 or size 19 or size 17, but a different size is indicated on the silicone flange, how come?

If you have chosen a size between 21, 19 or 17 you will find inserted inside the breast pump the bell with your correct size: even if you read a different number on the outer silicone flange, check that inside the milk extraction hole is the correct size insert.


Does the breast pump stay attached to the breast without any support?

NO, the breast pump is not designed to stay “glued” to your breast without any support: for proper use, you must use a bra (preferably nursing) that can hold your Mamashy.

I experience discomfort/pain while using the Mamashy, for what reason?

Most likely you have chosen the wrong size: the correct size is the one that allows the nipple not to rub on the outer edges of the silicone (in this case you have chosen a size too small) and not to pull on the nipple as well as the halo (in this case you have chosen a size too large). If you fall into these two cases, you do not need to return your Mamashy but can simply contact our assistance.

Contact us on Whatsapp number we will send you the correct size.

I chose the wrong size of my breast pump what can I do?

Don’t worry, if you have chosen a size 21 or 19 or 17 and realize it is too small, you can try removing the bell inside the extraction hole. Should this solution not be enough, please feel free to contact us, and we will send you the right bell for you.




How can I sterilize the breast pump?

For proper sterilization, use a common commercially available sterilizer; alternatively, you can immerse the components in water brought to a boil.

I notice milk leaking from the inlet hole, is the breast pump defective?

Before you make your M’AMASHY try to separate all the components, take the check valve, Which you can see in the picture, and check that the spout opens for proper milk flow, if it does not open squeeze the spout on the wide part between your fingers, you will see that it will open.
