Does Tafe have a child care curriculum? Like for working in daycare? That could kill two birds with one stone - give you a marketable skill, plus give you the skills to take care of your own children in the future. Or even just help with your niece.

One time i visited a friend, a single mom, who had her second baby. She made me give it a bottle, then she pointed out the milk was going in the baby's ear. I think i just dont have the mommy gene.
