A Victorian woman could be jailed for up to five years for getting her young son drunk on home-brew.

The crown prosecutor is appealing against her suspended sentence.

Kylie Jayne Eastwood, 34, formerly of Moe, was given a five-month suspended sentence for giving her son shots of grappa in July 2008.

The crown prosecutor is appealing against the leniency of the sentence and today told the County Court the five-year-old boy recorded a blood alcohol reading of 0.09 in hospital.

The prosecution alleged Eastwood gave her son up to six shots of liquor but the defence accused the boy's father of supplying the alcohol and "setting up" his estranged partner.

The judge found Eastwood guilty of reckless conduct endangering serious injury.

The hearing continues.
