Final answer:
Using too much diaper rash cream can lead to irritant dermatitis and worsen skin irritation. Overusing baby powder poses respiratory risks and other health concerns. It's essential to follow product guidelines and consult a healthcare provider for persistent or worsening rashes.
Step-by-step explanation:
The risks of using too much diaper rash cream or baby powder include the potential for causing or worsening irritant dermatitis. Excessive application of diaper rash cream, especially those with fragrance or certain ingredients, might irritate a baby's sensitive skin rather than protect it. Conversely, overusing baby powder can lead to respiratory issues if inhaled by the baby, and talcum-based powders have been linked to health concerns. It's crucial to use these products as directed and to seek alternatives if a rash persists or worsens.
