From one bottle to a feeding system the household keeps buying

Feeding is not a single purchase, it is a two-year sequence. A parent buys one bottle to find out whether the baby will accept it; if it works, they buy three more, then faster nipple flow rates as the baby grows, then replacement valves, then the sippy transition cup, then the parts that wear out.

The brand made every one of those products and sold them as twelve unrelated detail pages. Nothing on the starter bottle indicated that the rest existed, and the nipple flow stages were buried in a variation dropdown labeled in numbers that meant nothing to a first-time parent. So the sequence happened, but mostly with other brands: the customer's second purchase went to whoever's listing explained what they needed next.

We made the system visible from the first purchase.

• The starter bottle as an entry point, with A+ content laying out the full sequence and where the parent currently stands in it.
• Flow stages relabeled in human terms — age, and what the baby is doing — instead of numbered part codes.
• Multi-packs and stage kits for the points where parents predictably buy several at once.
• Replacement parts made findable, with the wear parts explicitly named in search terms because a parent hunting a lost valve is the easiest sale in the category.

Twelve-month revenue per customer rose from $27 to $94, and monthly revenue nearly doubled.

Acquisition did not change — roughly the same number of parents try the starter bottle each month. What changed is that they now know what the brand makes for the next six months, and the moment they need it is the moment they are told about it. The repeat rate more than doubled to 51%, which also makes the advertising work differently: a first order can be bought at close to break-even when the account knows what follows it.
