Past ventures




Blossom delivers online education to expectant and new parents. Their aim is to ensure that all parents are able to access impartial, evidence-based education that increases confidence and enables them to have a positive start to their parenting journey.

Classes are real-time, flexible and affordable and always offer the opportunity for parents to have their questions answered.

Their outcome data shows that their offering promotes good mental health and wellbeing, reduces isolation and loneliness and supports the parent-infant child relationship which plays a vital role in secure attachment with all the benefits that brings.

Blossom’s vision is to bring about systemic change so that all new parents feel supported and are able to access the help they need.

Blossom’s mission is to reduce isolation, improve mental health outcomes and facilitate positive parent-infant relationships through their bespoke educational offering. Parents who feel supported and are able to access education in a non-judgemental environment are better equipped to build nurturing relationships with their babies. At the heart of the work is a promotion of secure attachment and all the benefits that brings to the child, family and society as a whole. Building a happier, healthier and more nurturing world benefits all of humanity and this is Blossom’s ultimate goal.
