Sadly, her son died Jan. 23.
Spears regularly took to her blog and social media to report on her son's illnesses, and seemed to be a doting mother.
But investigators tell a different story, claiming Spears had been poisoning the boy with toxic levels of sodium through a feeding tube the whole time. (Via CNN)
And they say they have a smoking gun.
There are "two pieces of damning evidence — Spears' own computer seized by police found to have searches for poisoning children with sodium and a feeding bag said to be laced with lethal levels of salt," WPIX reported.
Authorities now say Spears could be have a syndrome known as Munchausen syndrome by proxy.

According to WebMD, the syndrome is characterized as "a mental health problem in which a caregiver makes up or causes an illness or injury in a person under his or her care." Attention received for having a sick child often encourages the behavior.
A psychologist not involved with the case told WABC that Spears seems to fit the profile.
"By involving social media, you can get all of that press, or attention, and feel a sense of importance," said Dr. Richard Filewich. "These are people who probably as children were themselves neglected or abused."
Spears is due back in court July 2. She is currently being held without bail and could face life in prison if convicted.
