Signs of heat rash

  • Tiny pimple-like bumps in folded areas, such as elbows, behind the knees, or neck. However, the upper chest and back are also prone to heat rashes.
  • Your baby becoming irritable.


  • Keep your baby’s skin cool. In the case of winter heat rash, avoid swaddling your baby too much or too tight. If possible, try to use breathable swaddle blankets. During summer, try to let your baby remain naked for the majority of the day.
