Yellow Rabbit tells parents "we size our baby clothes by weight, not age" and "just look at your baby's current weight". But on the product pages every size button is an age ("0-3 Months / 3-6 Months / 6-12 Months"), no product mentions a weight, and the kg ranges sit on a separate Size Chart page. The same size is also spelled six ways ("0-3 Months", "0- 3 Months", "0 - 3 Months", "0-3Months"...), which splits the Shop by Age filters. A parent with a 7 kg four-month-old still has to guess.

Why it works
Rename the size values on all 104 sized products to one weight-first format from your own chart, e.g. "4-6 kg (0-3 m)", "6-8 kg (3-6 m)", "8-10 kg (6-12 m)", "Preemie (under 2.5 kg)". Merge the spelling variants so each size exists once, then point the Shop by Age menu at the cleaned values (or rename it Shop by Weight). Add a one-line "Not sure? Weigh your baby, pick the kg range" note and a link to the chart above the size buttons.
The parent decides at the size buttons, not on a separate chart page. Showing the weight there delivers the promise the blog makes, cuts wrong-size orders, and matters more because returns are store credit only and the parent pays the return postage.

ChecklistWeight-first size labels
000 -> "4-6 kg (0-3 m)" 00 -> "6-8 kg (3-6 m)" 0 -> "8-10 kg (6-12 m)" 1 Year -> "10-12 kg (1 y)" 2 Years -> "12-14 kg (2 y)" 3 Years -> "14-16 kg (3 y)" 4 Years -> "16-18 kg (4 y)" 5 Years -> "18-20 kg (5 y)" Newborn / New Born / New born -> "Up to 4 kg (newborn)" Premie -> "Preemie"
Risks and how to handle them
Old links and saved carts break
Keep the variant IDs and only rename the values.
Parents still think in months
Keep the month range in brackets after the kg range.

- Your websiteRabbit Tales post "Why Yellow Rabbit Uses Baby Weight (Not Age!) To Help" (June 26, 2025): "we size our baby clothes by weight, not age or measurements"; "You just look at your baby's current weight, and voila - the right size is right there"; the post cites returns caused by incorrect sizing and promises "fewer returns".Source
- Store catalogueProduct data (118 products, October 20, 2026): 104 have a Size option and every size value is an age, with no weight in any size name or product description. The same size is spelled many ways: "0-3 Months", "0-3 months", "0- 3 Months", "0 - 3 Months", "0-3 Months", "0-3Months"; "Newborn", "New Born", "New born"; "1 Year", "1 year", "1Year", "1 Year (12-18m)", "12-18 Months (1 Year)"; "Premie" for the Preemie range. The patchwork romper page, for example, offers "0-3 Months / 3-6 Months / 6-12 Months".Source
- Your websiteSize Chart page (checked October 20, 2026): a table of "SIZE / WEIGHT / HEIGHT / AGE GUIDE", e.g. "000 4-6 Kg Up to 62 cm 0-3 Months", "00 6-8 Kg Up to 68 cm 3-6 Months", "0 8-10 Kg Up to 76 cm 6-12 Months", "2 Years 12-14 Kg Up to 92 cm". It is a separate page; the size buttons on product pages show only ages.Source
