The toddler dialed 911 a total of seven times last Thursday and nine other times before that, dating back to January.
May told KGW she was in the bathroom Thursday when her daughter Ayla found her phone and started playing.
After the sixth call, an officer gave May a warning. But when it happened again, she was cited for abusing 911. If convicted, she could face up to a year in jail and a $6,000 fine.
