A. For a 3-month-old baby with lumps and rashes all over the body, it's crucial to seek medical attention promptly. Here are a few steps you can take while you wait for professional medical advice: 1. **Keep the Baby Comfortable**: Ensure the baby is in a comfortable environment with loose, soft clothing that won't irritate the skin further. 2. **Avoid Known Irritants**: Try to avoid using any new products such as soaps, lotions, or detergents that might be causing an allergic reaction. 3. **Maintain Good Hygiene**: Keep the baby’s skin clean and dry. Use gentle, fragrance-free baby wipes and give regular baths with lukewarm water. 4. **Hydration**: Ensure the baby is well-hydrated, whether through breast milk or formula.
