A real gap in the reviewed chart
The maker's big-kid chart lists 6 Y and 8 Y but no 7 Y row. Its 6 Y height range is 42.5–47.5 in and 8 Y is 50.5–53.5 in,with different weight intervals. We do not invent a 7 Y range by averaging endpoints or fill the spaces between ranges with an implied fit rule.
A gap is not a rejection diagnosis
Unknown means this limited source record has no matching row. It does not prove a particular child cannot wear a product or that a new size should be ordered. The tool displays the missing status and a link to the maker. Personal fit requires evidence beyond a chart index.
Do not borrow another brand’s chart
A 7 label elsewhere does not complete the Burt's Bees Baby chart. Different brands and styles may use different systems. Similarly,24 M and 2 T are distinct native labels in this maker's record rather than interchangeable age aliases. Keep the source family and row name attached to every copied range.
Boundaries can overlap
The 4 T and 5 T rows share a stated height endpoint of 41.5 in. That does not authorize a universal algorithm choosing the bigger or smaller row. Our lookup does not take child measurements,so it does not resolve overlapping or discontinuous conditions into a recommendation. It simply preserves the rows as printed.
Ask a bounded question
Contact the maker with the exact style and requested native size or missing measurement. Keep any clarification with its date and product code. Do not size up snug-fitting sleepwear merely to avoid a chart gap. Current labeling and independent textile/safety review remain pending.
