Benadryl (diphenhydramine) is sedating: As you likely know so it is important todose appropriately. A number of sources are available, here is one: http://www.thhpediatrics.com/wp-content/themes/thhpeds/pdf/DiphenhydramineOption1.pdf

0.5 to 1.0 mg/kg: So if she is 29lbs she weighs about 12-13 kg. Benadryl (diphenhydramine) liquid comes 12.5 mg/5ml. I would say 5 ml would be a good dose. If she has never had it before you can start on the lower end with 3 ml and see her response
