Benadryl for a 18 month old?

Safe or not? Elise has a rash in her face. I know if I call her pedi office they will say not to give any because they never ever give any kind of medication to kids.

      Half the suggested dose, and put breast milk on the area it'll help.

          James' doctor actually told me to use Benadryl when needed. His doctor said in small doses, it should help. James has had it since he was about 18 months or so. He gets a really bad rash at times and it helps. They also recommended it for his car sickness.
