Brown's labor - his sentence in the 2009 beating of then-girlfriend Rihanna - is under scrutiny by a judge and prosecutors in Los Angeles, where he remains on felony probation.
An analysis by The Associated Press shows Brown's community labor credits dramatically increased in the past seven months, with the Grammy-winning artist working double shifts.
He has kept a high profile as well, performing at awards shows and releasing a new album.
The administrator of the daycare says Brown only worked on nights and weekends and described his work favorably.
