How it works

The Medela pump adapter threads a Medela pump directly onto the GentleBottle, so milk goes from pump to fridge to feed in one vessel. Skipping the pour from a collection bottle means no milk left on a second container's walls and one less piece to wash after every session.

Why parents choose it

  • Threads a Medela pump directly onto the GentleBottle
  • No second collection bottle to pour from or wash
  • Cut to the Medela pump thread, with the GentleBottle on the other end
  • Two adapters, so one can stay packed in the pump bag

Who it is for

Good fit for
  • Pumping straight into a GentleBottle with a Medela pump, with no transfer step.
  • A GentleBottle owner who already has a Medela pump.
  • Two adapters, so one can live in the pump bag.
Not right for
  • Spectra pumps. There is a separate Spectra version.
  • Any pump that is not a Medela. This adapter is cut to the Medela thread and nothing else.
  • Anyone without a GentleBottle.

Pumping directly into the bottle baby feeds from cuts transfers, washing, and milk loss, this adapter makes that workflow possible for Medela users.

More about this one

Which Medela pumps does it fit?

The Olababy Medela adapter fits Medela pumps that use the Medela pump thread, since it is cut to that thread and nothing else. It is not made for Spectra pumps, which have a separate Olababy adapter, or for other pump brands. You also need a GentleBottle, because the other end of the adapter threads onto that bottle.

What is included

2 adapters for Medela pumps. They connect a Medela pump to the GentleBottle.

How to clean it

Dishwasher safe (top rack).

Highlights

  • Rated 5 out of 5Verified buyer

    Saved me

    This bottle save my trip to Mexico. I’m leaving soon to Mexico and my baby is staying with my husband so I wanted to start giving him bottles. But every bottle we tried giving him he would fight and cry. I came across these and he fought for a few seconds then took them. I was so happy. I recommend these to ANY mom!

    Doesn’t fit all Medela products.

    I have the Medela Freestyle and these do not fit those pieces. However, my husband broke the sides off of my pump parts so that they would fit. It isn’t pretty but it works and I love pumping into Ola Baby bottles!

    Doesn't screw on properly and leaks

    In theory, this is fantastic, but for some reason the threads in the adapter don't line up with the GentleBaby bottle. The result is that you end up with one very specific point of leakage (and of course, that's the point that was pointed down for me when I was pumping). Looks like I'm not the only one having this issue.

    Doesn’t screw well but still helpful

    This adapter fits my Medela pump great, but the thing that’s weird is that it doesn’t screw onto my Ola Baby Gentle Bottle properly. It’s more like you have to push to pop it on rather than screw. So when I go to remove the adapter from the bottle, it’s a little tricky and I always end up spilling some milk. I still use it because I don’t want to pump into the plastic medela bottles, but it just seems like this should be an easy fix since it’s just a simple plastic part. The part that screws onto the bottle also has a kind of jagged edge on mine.

When can a baby start baby led weaning?

The American Academy of Pediatrics says babies are usually ready to start solid foods at around 6 months, and that some infants may be ready as early as 4 months. It adds that each child's readiness depends on their own rate of development.

Why does letting a baby feed themselves matter?

Leslie Schilling, a registered dietitian nutritionist and co-author of a book on baby led weaning, writes in Today's Dietitian that self feeding is a natural first step that can build feeding confidence and oral skills, and can help prevent overfeeding.

Does baby led weaning help a baby learn when they are full?

Laura Lucas, a senior clinical dietitian at Texas Children's Hospital, says one of the main benefits of baby led weaning is that it helps babies learn to recognise their own satiety levels, and that with proper handling and supervision it is safe for most babies who are developmentally ready.

What skills is a baby practising when they feed themselves?

Kimberly Churbock, a physician writing for Cleveland Clinic, describes a baby picking up a piece of food, bringing it to their mouth, manipulating it, chewing and swallowing, and notes that all of those actions require fine motor skills and oral motor skills.

What if my baby is unsure about a new texture?

Amy Klein, an occupational therapist at Cincinnati Children's, writes that for a baby who is not sure about a new taste or texture, self feeding gives them control to manipulate it in their mouth and swallow it or not, and that it also aids hand eye coordination.
