Hi Sian, is your product available in the resource magazines that go out to daycares centres/education facilities? When I was a teacher I used to order everything from Modern Teaching Aids, even the furniture for my classroom. https://www.teaching.co.nz
Your product is fantastic, I agree with the advice above, a complete end to end commerce website is going to capture so many more sales for you and then you can target your niche customer through FB ads. I love your work!
