I've got mine on shelves in the bathroom which are totally toddler proof. A lot of nappies were in the wash as the shelves look a little bare.
Top shelf (l to r) is csp, fleece, nursery nappies aka Easyfits, training pants
Bottom shelf is wipes, liners, night nappies, fitteds & wraps, day nappies
Photo will probably be cut off so the stack of Tuttos is missing. No idea why it does this.
