Officials say 36-year-old Sayyadina Thomas approached the toddler and his nanny at People's Park on Monday around 3:30 p.m.
Police were called and the suspect was taken into custody for a psychiatric evaluation.
While the nanny initially checked the boy's mouth and didn't find anything in it, while en route to the holding facility, police say the suspect told paramedics she'd given the child methamphetamines.
The child was taken to the hospital where staff confirmed what Thomas admitted to.
The child is recovering at the hospital while the suspect has been arrested for attempted homicide.
Anyone with information about the case is urged to contact the University of California Police Department Criminal Investigation Bureau at (510) 642-0472 from 8 a.m. to 5 p.m., except holidays, and (510) 642-6760 all other times.
