Court documents say Jasmine ignored lifeguards whistles ordering her to stop putting her son in danger.
"You can't do that, you have to stop," said one lifeguard.
Investigators say she continued to dunk the baby and eventually he lost consciousness.
Lifeguards reported the one-year-old was not breathing and had to revive him on scene. While Jasmine appeared in court, her mother talked with ABC13 from their southeast side home.
"Is she someone who would intentionally hurt her child?" asked Eyewitness News Reporter Christine Dobbyn.
"No, she wouldn't hurt him, she loves him, "Joyce Wallace responded.
As Wallace talked to ABC13, the one-year-old the mother is accused of dunking stood beside his grandmother, she says he is in good condition now.
She has custody of him along with Jasmine's other child.
While Wallace defends her daughter and says she's a loving mother, she says she does not know why her daughter allegedly put her grandson in so much danger.
"She really misses her baby and he misses her. I want her to get back with her baby," said Wallace.
