After a baby is bitten by insects and develops dark spots, parents can take the following measures:

1. Observation and care: Monitor the size and color of the dark spots. Usually, these spots fade away on their own over time and require no special treatment.

2. Medication: If the dark spots persist for a long time or if you wish to accelerate the recovery, topical medications such as human epidermal growth factor gel or vitamin E cream may be used under a doctor's guidance to help lighten the spots.

3. Sun protection and care: Protect the skin from sunlight in daily life to prevent further darkening of the pigmentation. Also, prevent the baby from repeatedly scratching the affected area to avoid infection or worsening inflammation.

4. Professional treatment: If the dark spots are severe or do not fade over time, professional treatments such as laser pigment removal may be considered.
