Legal Question about First Offenses?

My sister was recently arrested for shoplifting. She stole a pair of jeans and a vest from a department store, was caught, apprehended and taken to the police station. She was released 45 minutes later, she has NO criminal record and this is her FIRST offense. The total value of the items stolen were around $105 and they were taken back by the department store. She has a had a couple traffic tickets, one in which her license was suspended because of an unpaid ticket, but that was resolved immediately. Her concern is that she will go to jail, because it is her first offense and the monetary value of the items is so small in retrospect, I am trying to console her. I sincerely doubt she will go to jail, my guess is that she will receive some sort of fine, possible community service and/or probation. Can anyone shed some light on this? Also she is pregnant with her second child and a recent single parent, will this play into account? Could anything happen to her children? Can anyone shed some light on this please? Thank you.
