Welcome to the forum.
Regarding your baby sign issue, you need to understand that even though you have an SVG file, you don’t necessarily have a file that the Glowforge will print in the way you wish. To differenciate different operations, the Glowforge uses colors. In Inkscape, make different parts of your design different colors so the Glowforge can treat them differently. Also, only vectors can be cut/scored rather than engraved. After working through the Glowforge tutorials, I suggest reading the Laser Design Basics.pdf: Laser Design Basics 🤔
