Baby acne appears as small red or white bumps on face (cheeks, forehead, chin). Develops around 2-4 weeks old, caused by maternal hormones still in baby's system. Looks like teenage acne but smaller. Completely normal and common (affects 20-40% of newborns). Usually resolves on its own by 3-4 months without treatment or scarring. Not caused by poor hygiene.

Baby nails grow surprisingly fast and are sharp - can scratch face easily. Newborns often need nails trimmed 1-2 times per week. Baby nails are soft and flexible, making them tricky to cut. Attached to skin closer than adult nails, so easy to accidentally nick skin. Best time to trim: When baby is sleeping or right after bath (nails softer). Use baby nail clippers or emery board.

Newborns only need 2-3 baths per week (daily baths can dry skin). Sponge baths until umbilical cord falls off (1-3 weeks), then can do tub baths. Bath temperature: 98-100°F (lukewarm, not hot). Test with elbow or bath thermometer. Room should be warm (75°F+) to prevent chilling. Keep baths short: 5-10 minutes max. Use gentle, fragrance-free baby soap sparingly - water alone is fine for most of body.
