Frequently Asked Questions

How much milk can I store with Maia?

We claim with confidence that Maia stores up to 10 ounces of milk at safe temperatures for 16+ hours. Maia’s Bottle component has ounce markings that measure up to 10 ounces, and enough room to accommodate an extra ounce if needed.

Looking for more than 10 ounces of milk storage? Think about purchasing two Maias together - you’ll get an automatic 20% off the order.

What pumps are compatible with Maia?

Maia is directly compatible with the connectors on standard-mouth pumps like those made by Medela*, Ameda, and Evenflo. If using a wide-mouth pump (e.g., Spectra), use the Adapter provided with purchase of Maia (look at the bottom of the box). 

Do you instead use a wearable pump like those made by Willow or Elvie? Many of Pippy Sips’s customers do, too - they simply pour milk from their pump into Maia’s Bottle. 

Ultimately, no matter which pump you use, there is a way for Maia to upgrade your pumping experience.

* Note: Maia does not fully integrate with Medela’s Freestyle Flex pump, which has connectors that are designed differently than those of other Medela pumps. If you have a Freestyle Flex, you’d use Maia in the same way as our customers with Willow or Elvie pumps.

How do I check the temperature of the milk I’m storing in Maia?

Use your finger to double-tap on or near the screen of the Thermo-lid. And don’t be afraid to tap with some emphasis! Alternatively, you can give Maia a brief shake back and forth in a windshield-wiper motion to reveal the temperature on the screen.  

Can I sterilize Maia’s plastic Bottle in boiling water?

Yes, it is safe to boil the Bottle for as long as you would any other plastic pumping accessories (many sites recommend 5 minutes). Just note that, as with frequent runs through the dishwasher, frequent boiling of the Bottle over time may cause the artwork (including the ounce markings) to fade. 

Is it okay to mix freshly expressed milk from my current pumping session with already chilled milk from my last pumping session?

Yes. In other words, it is safe to use Maia as directed. 

We’re aware that the American Academy of Pediatrics (AAP) updated its breastmilk storage guidelines in early 2021 to reflect that “Mothers can mix warm milk and cold, or even consider pooling milk from 24 hours together, which may help even out variability in nutrients due to pumping time or breast emptying (which influences fat content of the milk).” And we’re aware that the AAP no longer highlights that guidance on its website (a change that occurred not long after this post on Mother.ly). We’re also aware that the Centers for Disease Control and Prevention (CDC) advises against mixing warm and chilled milk, out of fear that the chilled milk will “rewarm.”   

Naturally, adding warm liquid to cold liquid will cause the temperature of the cold liquid to rise at first. A reliable cooling mechanism, however, will bring the temperature back down. When storing breastmilk, it is important to reference the storage-temperature guidelines, from the CDC and other entities. As you’ll see in the Maia User Manual, breastmilk can be safely stored at room temperature for 4 hours, and under 59° F for 24 hours. Maia adheres to those guidelines, using active cooling (from the Puck) and insulation (from the Shell), among other things.
