Dear Parents! This is us – the girls behind Whisbear!

Our mission from the beginning was and is to support young parents – as mums ourselves, we were initially completely lost, we often felt helpless, unprepared for the role of a parent. We were particularly bothered by the lack of sleep and that is why our flagship products are the Humming Cuddly Toys which help babies to calm down and fall asleep. We promote the idea of IMPERFECT parenting. We know that although parenting is a beautiful adventure, there are many unforeseen twists and turns, and moments of doubt – this is where we, at Whisbear, want to support you, parents.

We are young mothers and we have also tested the effectiveness of pink noise as an answer to children’s crying and parents’ frustration on our own children. It all started with the vibrant sound of the hairdryer, which more than 11 years ago soothed the crying of the first son of Zuzia Sielicka-Kalczyńska – the co-founder of Whisbear. This noise transformed a difficult parenting experience and a struggle with painful colic into an idea for the first Polish Whisbear Humming Cuddly Toy. Three years later, we introduced the world to the Whisbear Humming Bear, now known as the Whisbear Sensory Humming Bear, which quickly became a recognized, recommended, certified and award-winning product, and Whisbear became a globally recognized brand.

Whisbear is the only company in Poland to receive a Positive Opinion from the Polish Institute of Mother and Child, which is a guarantee of product safety. We were also honoured as one of the most entrepreneurial young women in the world at the Global Entrepreneurship Summit in Nairobi, held under the patronage of Barack Obama, the then US President. Even Duchess Kate, who received a Humming Bear from our team after the birth of Princess Charlotte, trusts The Whisbear brand and a few years later awarded us with the “Warsaw-London Bridge. Health Tech Award”.

We are here for you, making sure that every Whisbear product you invite into your home meets all your expectations and takes care of your little one’s peaceful sleep.

Thank you for trusting us!
