It sounds concerning that the insect bite area now looks like a burn with fluid, which may indicate infection or a severe skin reaction. You should avoid applying any creams without a doctor's advice and keep the area clean and dry.

• Monitor for signs of worsening infection such as increased redness, swelling, warmth, spreading rash, or fever.
• Do not burst any blisters or fluid-filled areas to prevent further infection.
• Since the area looks like a burn with fluid, it is important to have a pediatric dermatologist or a pediatrician examine your baby promptly.
• If you notice any difficulty breathing, swelling of the face or lips, or if your baby seems very unwell, seek emergency care immediately by calling Apollo Emergency at 1066.
