A judge told jurors at the High Court in Edinburgh that it was a "rather distressing and unpleasant case" but noted that the boy "happily appears" to have made a "good recovery" from his injuries.
Lawrence, was originally charged with attempting to murder the baby on 4 December 2020 at an address in Falkirk.
A jury at her earlier trial acquitted her of that charge but found her guilty of assaulting the child to his severe injury and to the danger of his life.
Lawrence was convicted of inflicting trauma to the head of the baby by means to the prosecutor unknown and by shaking him.
She was also found guilty of wilfully exposing the child in a way likely to cause him unnecessary suffering or injury by burning his body with a hairdryer.
Lawrence was acquitted of a further allegation that she exposed the child to cocaine and amphetamine and caused him to ingest the drugs.
She had denied the offences at the trial and the court heard she continues to deny causing injuries to the child.
