The customer's problem
Baby Studio serves a very specific group of shoppers: parents, young families, and people buying gifts for little ones. For this group, the need is usually clear, but the path to the product branches in many directions: strollers, car seats, nursery, feeding, baby care, toys, accessories, and product groups organized by age or use case.
When a catalog has this many groups, the theme's default menu starts to run out of room. On desktop, a flat menu bar can't convey the full breadth of the store. On mobile, if everything is hidden behind a hamburger menu, customers have to open each level themselves and guess which group holds the product they need.
The problem isn't a lack of products. The problem is that the products are good, but the navigation structure doesn't help customers see what the store sells, so they spend extra steps finding the right area. On mobile, a few extra steps are enough for a customer to skip an important product group.
