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.

Questions parents ask
What comes in the box?
2 adapters for Medela pumps.
How do I clean it?
Dishwasher safe (top rack).
What is it made of?
BPA-free PP material. Designed in Portland, Oregon.
How big is it?
It measures 4.5" x 5.5" x 2". It weighs 1 oz.
Will this work for a breastfed baby?
The GentleBottle system was designed specifically for breastfed babies, with a soft squeezable body and off-center nipple that mimics a natural latch to reduce bottle refusal.
What should I look for in a bottle for a newborn?
A slow, controlled flow and a soft nipple that supports a deep latch. The GentleBottle’s off-center nipple angles toward the palate and paces milk like nursing, and the 4oz size suits early feeds, which is why parents searching for the best bottles for breastfed babies so often land on it.
Are glass or plastic baby bottles better?
Both have trade-offs, which is why we chose a third material. The GentleBottle is 100% food-grade silicone (free of BPA, PVC, lead, and phthalates), so it will not shatter like glass, and the soft body compresses in a baby’s hands like skin. It goes in the dishwasher (top rack) or a steam sterilizer without breaking down.
When should babies stop using bottles, and how do we wean?
Pediatric feeding specialists suggest weaning off the bottle by 12 to 18 months, and gradual works best. The GentleBottle Transitional Set moves from nipple to teether handle to sippy lid on the same familiar bottle, so your baby changes one skill at a time: the sippy lid turns it into a soft-spout cup for the transition from bottle to sippy cup, and open-cup practice can start around 6 months.
How often should I replace bottle nipples?
Inspect nipples monthly and replace roughly every 3 months, or sooner if you see thinning, clouding, or tears.
Is this safe for my baby?
Yes. Olababy feeding products are made from 100% high-purity food-grade silicone with no fillers, free of BPA, PVC, lead, and phthalates, and tested to FDA food-contact standards.
How do I clean and sterilize it?
Silicone products are dishwasher safe (top rack) and can be sterilized in boiling water or a steam sterilizer. Air-dry fully before storing.
What if it does not work for us?
Returns are accepted within 30 days of delivery (see our return policy for details). US shipping is free on orders over $49.
Why buy from olababy.us instead of a retailer?
Olababy.us is the official store and the only place with the complete lineup: every product, every colorway, replacement parts, and bundle pricing. Orders over $49 ship free in the US, returns are accepted for 30 days, and support comes directly from the Olababy team.
Why Olababy
Every feeding product is one material, food-grade silicone, soft enough for gums that are still teething and inert enough to go through a dishwasher for years. The panel above names what is in it and what is kept out of it.
Olababy has designed in Portland, Oregon since 2015, with parents testing the things their own children eat from.
US shipping is free over $49 and returns run for 30 days from purchase.
