For babies with eczema or persistent dry skin, keeping the skin barrier hydrated is essential. Pediatricians often recommend fragrance-free, medical-grade moisturizers like Physiogel or Aveeno (especially their 'Dermax' range). Use lukewarm water for baths rather than hot water, which can strip away natural oils, and apply moisturizer immediately after drying to lock in hydration. Always consult your pediatrician for a formal diagnosis to ensure you are using the right product for your baby's specific skin barrier needs.
