When giving your 6 month old baby Benadryl they can take 1 tablespoon of Benadryl.
A 6 month old will need to take the liquid children's Benadryl and not the pill form as the pill form can choke them.
Make sure you just give the 6 month old the liquid form of Benadryl and they will be safe.
Never give a baby under 6 months old any Benadryl as it can harm them.
But at 6 months of age and above they can take Benadryl.
The recommended amount and safe dosage of Benadryl for a baby 6 months of age to 11 months of age is 1 or 2 tsp (5–10 mL) every 4 to 6 hours.
