Bare® Air-free vs. baby bottles

Bare® Air-free difference

Most breast-like

compare bottles
This comparison is based on published articles, factual statements, and user testing.
1 Bare®, as well as bottles with liners, allow the user to expel air. It is known that air-swallowing may cause gas/colic in babies. The less air ingestion the less gas in babies.
2 Nutrients are lost when milk is mixed with oxygen in the air, Bare® allows the user to expel the air and maintain an air-tight container to inhibit bacteria growth, due to the lack of oxygen, resulting in longer nutrient retention than baby bottles that allow air. A baby bottle with collapsible liners allows the user to expel air but doesn’t maintain an air-free environment, air goes back in almost immediately as gravity pulls liquid down.
3 Because Bare® works with suction as opposed to gravity, the baby is able to start feeding as soon as he/she can bring the bottle to his/her mouth. Other bottles require the baby to turn the bottle upside down which can delay the self-feeding milestone.
4 Breastfeeding directly is proven to have invaluable benefits for mom and baby rather than bottle-feeding breast milk to learn more about the advantages of breastfeeding go to;115/2/496


This Bare® Air-free is for babies 0-6 months with severe gas, spit-up, daytime fuss, midnight colic, GER, GERS & diagnosed GERD. Use the Perfe-latch® nipple if you are initiating, reinstating, or extending breastfeeding.

When to use

  • If your baby drinks less than 4oz of milk
  • Try Easy-latch® if your baby is bottle-fed
  • Try Perfe-latch® if your baby is exclusively breastfed

If you are using the Perfe-latch® nipple

Use as intended

Newborn upright feeding

Always feed your baby in a vertical-upright position (be sure the chin doesn’t touch the chest.) Follow step-by-step instructions.

Bare® Air-free is designed to feed while held right side up. DO NOT tip upside down nor hold horizontally. Let the baby create the suction to feed while in an upright position and against gravity.

The Perfe-latch® nipple extends upon suction to emulate the mechanics of breastfeeding to minimize nipple confusion. The Easy-latch® nipple is the easiest to latch on for bottle-fed babies. Both nipples offer Flow-Control® technology so babies control the flow and pace of feeding.

How to use Bare Air-free - sit down

1. Sit in a comfortable location. Be sure Bare® Air-free is prepared per instructions.

How to use Bare Air-free - Newborn feeding head support

2. Sit your baby on your lap and place the palm of your hand at the base of the baby’s head. Your thumb should be right behind one ear and the rest of your fingers behind the other ear to offer adequate head and neck support. Never position your fingers under the ears, this can be very painful.

Newborn upright feeding

3. While supporting the head and neck behind the ears, position the head with the face tipped down just a little bit. Avoid allowing the chin to rest on the chest. Hold Bare® Air-free right side up. The nipple should be higher than its base.

How to use Bare Air-free - proper assembly

Hold Bare® Air-free right side up and feed your baby while in an upright position. Let the baby control the flow with suction. Do not tip Bare® upside down. Do not hold horizontally while feeding.

Be sure the assembly is correct. If any of the pieces are not properly installed, you may have air leaks acting like an air-vents, introducing air in the container when the baby applies suction.

How to use Bare and adapt it to your baby’s feeding habits

Bottle-fed babies typically lose the ability to feed with suction, as traditional bottles often free-feed.

Bare® Air-free, on the other hand, promotes healthy suction-based feeding. Babies need to apply suction, in order to feed, like with breastfeeding.

You can customize Bare® Air-free to fit your baby’s suction patterns as well as match the flow and let down of your own breast. Not all babies have the same suction range, therefore you can get Bare® to adapt to your baby’s feeding habits, not the other way around. See more in the tutorial

  • Fill up a bowl with tap water, hot setting but tolerable to the touch
  • Dip Bare® in the bowl for a few minutes
  • Do not use bottle warmers
  • Do not heat with a microwave

  • Please make sure the nipple/collar/cylinder are assembled per instructions. See tutorial
  • If you have the Perfe-latch® nipple, refer to the video tutorial and see to expel the air
  • If you see air entering the nipple while the baby feeds, it could be as a result of the Air-plug® not moving with suction. Check the “how-to” page and refer to the section “The Air-plug® doesn’t automatically move as my baby feeds” to learn how to customize Bare® to your baby’s needs
  • Leakage from assembled parts are due to poor assembly
  • Please refer to the instructional video on the “how-to” page/tutorial to make sure everything is assembled properly.
