It is difficult to be sure about your baby son's skin rash without being able to see him.This is not due to chicken pox.If the blisters are small then they may be due to an allergic reaction to sand flea or mosquito bites, with sand flea bites being the more common cause. This condition is known as 'papular uricaria'. Have a look on Google: enter 'papular urticaria' and see if you recognise the blisters in the pictures.If you think your son has papular urticaria apply calamine lotion to the blisters. If the blisters are large about the size of a 20c or even a 50c coin then they may be caused by a bacterial infection due to staph bacteria.In this case you should see a dermatologist.
