Baby feeding is a compatibility business with a spare parts business inside it. A parent who has settled on a bottle will buy teats for it for the next year, then valves, then a straw for the cup, then the whole weaning set, and every one of those orders depends on knowing which part fits what they already own. Put the compatibility answers on the page and the repeat orders follow. Leave them in a manual and the customer buys the wrong teat once and never comes back.
We write growth plans for baby feeding brands that already sell online. The plan covers Shopping feeds that carry the flow rate, the volume and the material in the title, product pages that answer compatibility and cleaning questions in text, spare part merchandising that turns one bottle sale into a year of orders, and flows keyed to the feeding stage.
It also covers the market-by-market rules on advertising bottles and teats, which decide what your ads can say before anything else does.
The first purchase is usually a starter set bought before the birth or added to a registry, chosen on volume, material and the shape of the teat. Then the baby has opinions. Half the set is abandoned, and the parent buys more of whatever worked. That second order is the important one, and it is placed by someone who now knows exactly what they want and will not be talked out of it.
From there the questions are mechanical. Which flow rate comes next and roughly when. Which teats fit this bottle, and whether the ones from the older version still fit. Whether the bottle goes in a steriliser, a dishwasher and a warmer. What each part is made of. How many pieces there are to wash at two in the morning, which is a genuine purchase driver and almost never mentioned on a product page.
Weaning opens a second wave around the middle of the first year: bowls that suction to the table, soft-tipped spoons, open cups and straw cups, and bibs with a catch pocket. Some of it is bought as a set and some as a reaction to a mess.
The repeat is parts and stages. Teats wear and get replaced, flow rates go up, valves and straws are lost, and it all ends when the child moves to ordinary cups and cutlery.
