honey-acv-sleep — open questions

• Does topical medical-grade honey sensitise toddlers with broken eczema skin to bee products or pollen, and has any trial included children under 5?
• Is there a dilution of apple cider vinegar that lowers skin pH durably without irritation, and how would it compare head-to-head with dilute bleach baths?
• What do current UK prescribing references (BNFc) say about sedating antihistamines for eczema sleep loss in children aged 6–24 months, given NICE allows them from 6 months but Medsafe contraindicates them under 2?
