About Us Who we are and what drives us We’re not magicians. But as publishers, illustrators and authors, we’ve created numerous international children’s book titles and published them with some of the most renowned publishing houses — including the award-winning Bababoo and friends® series. First and foremost, though, we’re parents ourselves — supported by a 20-person team with decades of experience in childcare and toy quality assurance. We know the questions, the doubts — and the small moments that mean everything.

We created bluumy to save you time and to help you discover the right books to truly enrich your child’s early years. A meaningful children’s book has to fit your child — and you — first and foremost. That’s exactly where we come in: no advertising, no detours. Just directly for you and your family.
