Why does it appear
The exact mechanism is not fully understood, but it is believed that this is a normal transient reaction of the skin. After birth, the child first encounters air, clothing, bacteria that colonize the skin, and the immature immune system responds with an accumulation of special cells - eosinophils - around the hair follicles. They form a yellowish dot in the center of the spot. The condition is not related to the mother's diet, allergies, overheating or quality of care, so there is no need to change the diet of a nursing woman or look for an allergen. The rash is more common in full-term, normal-weight babies.
- Transitional state of the newborn period
- Skin reaction to colonization by microflora
- Accumulation of eosinophils around follicles
- Not related to maternal diet or allergies
- More common in full-term babies with good weight
What does it look like
Rashes usually appear on the second or third day of life, less often immediately after birth or in the second week. These are irregularly shaped red spots ranging from a few millimeters to several centimeters in diameter, often with a small bump or vesicle in the center. Favorite places are the face, chest, back, extensor surfaces of the arms and legs. It is very characteristic that the palms and soles remain clean. Elements migrate: in the evening they are in one place, in the morning they are already in another, and this is an important distinguishing feature.
- Appears on days 2–3 of life
- Red spots with a yellowish-white dot in the center
- Localization on the face, trunk and limbs
- Palms and soles free of rash
- Elements move and change throughout the day
- The child is not worried, there is no temperature
How to distinguish from a dangerous rash
The main guideline is not the rash itself, but the child’s well-being. With toxic erythema, the baby is active, sucks well, gains weight, and the temperature is normal. Anxiety should be caused by lethargy, refusal to eat, fever or, conversely, low temperature, gray skin tone. Also alarming are blisters with purulent contents, crusts and weeping characteristic of a staphylococcal infection, and small hemorrhages that do not fade when pressed with a transparent glass. A rash on the palms and soles of erythema toxicum is unusual and requires evaluation.
- Erythema toxicum - the child is healthy and active
- Vesiculopustulosis - pustules, requires treatment
- Milia - white spots on the nose, also harmless
- Miliaria - small blisters in the folds due to overheating
- Infectious rash accompanied by fever and lethargy
- Hemorrhagic rash - does not turn pale when pressed, see a doctor immediately
Baby skin care
No ointments, antiseptics, powders or herbal infusions are required, and attempts to treat the rash often do more harm than good. Regular careful care is sufficient. It is important not to overheat the child: overheating worsens rashes and contributes to heat rash. Dress your baby the same way you dress yourself, plus one thin layer. Short air baths are useful. You can bathe in clean water without adding potassium permanganate and herbal decoctions, which dry the skin and can cause irritation.
- Daily bathing in clean, warm water without additives
- Refusal of ointments, creams and powders on rash elements
- Air baths for several minutes
- Room temperature is about 20–22 °C
- Cotton clothes, no overheating
- Do not squeeze or open elements
When will it go away and do you need a doctor?
The rash usually disappears within a week, sometimes lasting up to two weeks, appearing in waves. There are no traces, scars or pigmentation left. An examination by a neonatologist or pediatrician is necessary in any case, since in newborns many diseases manifest themselves similarly, and the condition can change quickly. Planned patronage in the first days after discharge solves this problem. An unscheduled visit is mandatory if the alarming signs listed above appear, or parents are simply not sure.
- Resolution in a few days, maximum two weeks
- There are no traces or scars left
- Routine examination by a pediatrician after discharge
- Urgent assessment for fever and lethargy
- Photos of the rash will help the doctor assess the dynamics
- Do not change the diet of a nursing mother unless indicated.
