"Candle wax is considered nonpoisonous, but it may cause a blockage in the intestines if a large amount is swallowed. ... Symptoms may include rash or blistering of the skin, or swelling, tearing, or redness of the eye if it has been touched by the fingers which had contact with the candles." - Medlineplus.gov
and it depends if it was made with toxic wax or not read the lable of the candle! if it says its made of paraffin then that depends on how much he ate. if he ate alot that could lead to intestinal obstruction (when your large or small intestine is blocked)
