• Is there any paediatric RCT of topical calendula or chamomile for atopic dermatitis, and how often do Compositae-containing “natural” baby balms sensitise toddlers with eczema?
• Do specific probiotic strains (e.g. L. rhamnosus + L. casei) help a defined subgroup, such as under-2s with cow’s-milk allergy, despite the Cochrane 2018 null result overall?
• How common are undeclared steroids in “natural” eczema creams sold in South Africa and other non-UK markets, and what proportion of parents using them know?
• Does virgin coconut oil outperform a standard (non-mineral-oil) emollient in toddlers 1–4, and does it carry any food-allergy sensitisation risk through broken skin?
