improving quality of life

Babies with gas, fuss, colic, and recurrent GER (gastroesophageal reflux) can now experience mealtime without the painful symptoms. In a pilot study, Bare® Air-free feeding system provided relief to 75% of babies clinically diagnosed with GER. The magic is due to its patented syringe-like design, which allows true air-free milk, vertical-upright feeding position, and automatic pace and flow-control.

Bare Air-free is for babies 0-18 months with severe gas, spit-up, daytime fuss, midnight colic, GER, GERS & diagnosed GERD.

bare® story

Priska Diaz, M.S.
Founder & CEO of Bittylab
Mom-inventor of Bare® Air-free feeding system

After all the hard work to get my baby to breastfeed, I was crushed to learn that I had to supplement my feedings due to a low-milk supply. Bottle-feeding turned my baby into a crying machine for endless days and nights. The lack of available solutions added feelings of maternal failure to the ongoing sleep-deprivation, headaches, pain from c-section, and exhaustion. All I wanted to do was to stop his pain, so I rolled up my sleeves and began. After months of research, I learned that air in the baby bottles causes gas, which leads to colic and exacerbates GER (gastroesophageal reflux). Statistics show that 2 out of 3 babies experience the painful symptoms of GER. So, I worked at my kitchen table to design a solution that eliminates GER in infants.

After years of working with engineers, moms and doctors, I’m thrilled to share that Bare Air-free is clinically proven to reduce GER, has helped tens of thousands of babies overcome the painful symptoms, made the headline-news on many local and national outlets, and is recommended by pediatricians. I’m now on a mission to help parents raise their babies in a GER-free world.
