The dose of diphenhydramine is calculated as = 0.5 mg/pound

here the weight of the baby is 27 lbs

so according to the dosage it comes 0.5*27=13.5 mg is the safest dose

• Dose. Find the child's weight in the top row of the dose table. Look below the correct weight for the dose based on the product you have.
• Measure the Dose. Syringes and droppers are more accurate than teaspoons. If possible, use the syringe or dropper that comes with the medicine. If not, you can get a med syringe at drug stores.
