Only on july 3rd,2012 I saw your question posted on Jun 7th.Though clearly late, it may benefit people who face similar situation.
What is the rash
and why did it come? We will try to provide the answer.
All rashes, which are raised, are due to two reasons. Something wrong inside the body and something is coming from outside.
Inside the body it can be due to
1. Blood infections or problems
2. Urinary tract
3. Gut infection
4. Caries teeth.
With out high fever
blood problems are unlikely. More over the blood problems will cause lesions all over the body.
Same is the case with urinary infection, beside pain, itching, burning sensation while passing urine.
Gut infection can cause diarrhoea
, oil stained stools.
Of course 13 months usually will not have caries teeth.
Then the problem should have come from outside
Outside problems are in two groups
Through the mouth
1. The drugs we are giving
2. The diet we have given
B. Through the skin
1. Playing in the dust
2. Playing near plants
4. the dress we have used
we have used for bathing and washing clothes
Most probably your child had a combination these most probably child had a combination of the above six problems
the best first aid
is to use tap water sponging.
Most of the time the rash disappears
Hopefully your child has settled
