When a baby develops dark spots after insect bites, parents can take the following steps to manage them:

1. Observation and care: Monitor the size and color of the dark spots. These spots are usually the result of skin inflammation and post-inflammatory pigmentation following insect bites. In most cases, they will fade naturally over time without special treatment.

2. Medication: If the dark spots persist for a long time or if parents wish to speed up recovery, topical ointments such as recombinant human epidermal growth factor gel or vitamin E cream may be used under medical guidance. These products can help lighten the pigmentation.

3. Sun protection and skin care: Protect the skin from sun exposure, as UV rays can worsen pigmentation. Also, prevent the baby from scratching the affected area repeatedly to avoid infection or further inflammation.

4. Professional treatment: If the pigmentation is severe or does not resolve over time, professional treatments such as laser therapy for pigment removal may be considered.

With these measures, dark spots left by insect bites in babies can usually be effectively managed.
