After a relative noticed some unusual bruises on the child, she was subsequently examined at Wanganui Hospital on January 31, 2011.
She was found to have a 2cm scar to the right of her forehead and bruising to her arm and thigh.
Tehuna told police she smacked the victim on the bottom and hand once or twice a week and she sometimes noticed a bruise on the victim's bottom the next day, but denied the other allegations.
In relation to the theft charge, Tehuna was associated with a 60-year-old man who she took with her on shopping errands, and he in turn assisted her by providing transport.
Between March 15 and 19 last year, Tehuna took the man's ATM card and withdrew a total of $2800 in three separate withdrawals.
She told police she did withdraw the money, but had permission to do so.
While these charges were pending, Tehuna was convicted of drink driving and was sentenced to four months' community detention and six months' supervision in August last year.
Following that charge, Tehuna's lawyer, Peter Brosnahan, said she referred herself to alcohol and drug counselling and undertook and completed a residential alcohol program.
She successfully completed her community detention and continued to engage with those support networks, had not offended since and was clear of alcohol and drugs.
Tehuna had made huge progress in addressing her significant alcohol issues which underpinned her offending.
She had taken hold of her life and turned it around, he said.
Judge Cameron said Tehuna's pre-sentence report and two letters, one from a person identifying themselves as a social worker, had been handed to the court, describing how her relationship with the child in question was continuing to improve and they showed an excellent rapport.
