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.
