Hello
Based on your description, your child may be experiencing atopic dermatitis or seborrheic dermatitis, which often flares with triggers like heat, allergens, or irritants.
While homeopathy is commonly used by some parents, arsenicum album (ars alb) 30 is not scientifically proven to be safe or effective in infants, especially at 9 months. Its pungent smell might vary depending on the preparation, but that should not be the main concern—safety and efficacy are key.
It’s best to pause this medication and not continue unless specifically advised by a pediatrician who is monitoring your baby.
Next Steps
Continue using cloth diapers and ensure frequent changing to keep the area dry.
Use fragrance-free emollients to maintain skin hydration.
If the rashes worsen or spread, consult a pediatric dermatologist for a detailed evaluation and allergy testing if needed.
Avoid over-the-counter topical steroids without supervision.
Health Tips
Avoid self-prescribing or long-term use of alternative medications in infants.
Keep the baby’s nails trimmed and clothing light to reduce scratching and irritation.
Watch for signs of infection like pus, fever, or rapid spread of rash.
