SleekRank renders pre-defined age band pages (newborn, 1 month, 3 months, etc.). If you want an interactive age calculator that takes a birth date and shows the current age band and milestones, ship a small Alpine component that takes the birth date and surfaces the matching age band content. SleekRank handles the static SEO surface; the widget handles the date-to-age math.

Common patterns are: newborn through 3 months in weekly bands, 3-12 months in monthly bands, 12-24 months in 3-month bands, 2-5 years in 6-month bands. Granularity should match where parents have distinct concerns. Bi-weekly newborn bands are common because development changes fast in the first 12 weeks.

Define a separate page group at /baby-age/corrected/{slug}/ for preterm corrected age. The corrected age uses the same milestone arrays but anchored to the corrected age band (a 6-month-old born 8 weeks early uses the 4-month corrected milestone reference). Splitting cleanly handles the editorial differences without confusing parents of full-term babies.

Yes. Either use a feedings_breastfed array and a feedings_formula array in the same row and render both via separate list mappings, or split into parallel page groups at /baby-age/breastfed/{slug}/ and /baby-age/formula/{slug}/. Parallel groups suit clinical-leaning sites; combined rows suit lifestyle parenting publishers.

The sheet is the single source. When WHO or CDC publish growth chart revisions, update the weight, length, and head circumference columns and flush the SleekRank cache. Keep a growth_chart_source column noting which standard (WHO 2006, CDC 2000, WHO 2023) the row uses, surfaced on each page for credibility.

SleekRank caches the source per cacheDuration set in seconds. Edit the sheet, clear the SleekRank cache via WP-CLI or admin, and the next request rebuilds the page with new data. For pediatric reference content (a slow-changing domain) set cacheDuration high so the sheet is not constantly refetched.

Yes. Each generated URL is a real WordPress page included in the sitemap. The base template is excluded automatically so the scaffolding does not compete with real age pages. Run a rewrite flush after adding new slugs so the routes resolve immediately on production.

Yes. SleekRank ships with a related entries helper that filters by category and renders up to six related pages with a deterministic shuffle. Group ages by developmental stage (all infant pages, all toddler pages) and the related cluster forms automatically per page.
