Sn00zly's sleep guides — the four age-stage guides and the six supplementary guides — were reviewed for clinical accuracy by an independent board-certified pediatrician before publication. This page explains who did that, what they looked at, and — just as importantly — what the review does not mean.
Who reviewed them
Leah M. Alexander, MD is board-certified in General Pediatrics by the American Board of Pediatrics (ABP ID #617928) and licensed to practice medicine in the State of New Jersey (license no. 25MA07101100, New Jersey State Board of Medical Examiners). Both credentials are held in public registers and can be verified independently.
Dr. Alexander was engaged and paid by Sn00zly LLC to carry out the review. She has no ownership interest in the business and receives nothing from sales.
What was reviewed
Four age-stage guides, version published August 2, 2026:
- Newborn Sleep Guide (0–3 months)
- Baby Sleep Guide (4–6 months)
- Baby Sleep Guide (7–12 months)
- Toddler Sleep Guide (12–24 months)
Six supplementary guides, version published August 13, 2026:
- Sleep Nutrition Blueprint
- Nap Transition Kit
- Night Weaning Blueprint
- Travel Sleep Guide
- Sleep Regression Survival Kit
- Wake Window Cheat Sheet
What the review covered
Both reviews were limited to factual and safety accuracy against current American Academy of Pediatrics safe sleep guidance:
- Sleep position
- Sleep environment and sleep surface
- Bedding and soft objects
- Swaddling and the transition once a baby begins to roll
- Room-sharing
- Room temperature
- Introduction of solids and allergens
- Milk and feeding volumes, and night-weaning safety
- Age-appropriateness of the guidance
- Whether the caveats in the text are adequate
What came out of it
The first review (four age-stage guides, August 2, 2026) produced an issue log of specific corrections. All of them were applied before publication, and the corrected pages were returned to Dr. Alexander for confirmation before she signed off. Among the changes: the recommended room temperature was brought in line with current AAP guidance, white-noise volume guidance was lowered, swaddle instructions now carry a hip-safety note, and bedding wording was tightened throughout.
The second review (six supplementary guides, August 13, 2026) produced 34 further corrections, twelve of them major, again applied before publication and confirmed page-by-page by Dr. Alexander before she signed off. Among the changes: a rice-cereal recommendation was replaced with lower-arsenic alternatives per current AAP guidance, several allergen-introduction ages were moved earlier and several choking-risk food textures were moved later, and swaddle guidance was tightened to stop once a baby can roll.
What this review is not
This is the part most pages like this leave out, so it is worth stating plainly.
- It is not an endorsement. Both of Dr. Alexander's letters say so in terms: they do not constitute an endorsement of the product, a recommendation to consumers, or medical advice to any individual.
- It is not an AAP review. The American Academy of Pediatrics did not review these guides and has no involvement with Sn00zly. The guides were checked against published AAP guidance by one physician.
- It is not medical advice for your baby. Every guide carries the same line on every page, and it means it: educational content, not a substitute for individual medical advice. Your pediatrician knows your child; a PDF does not.
- It applies to specific versions. The first sign-off covers the four age-stage guides as published on August 2, 2026; the second covers the six supplementary guides as published on August 13, 2026. Material changes to a guide after its version date would void the sign-off for that guide, and we would have it reviewed again rather than quietly carry the claim forward.
