risotto: what BAD THING happens if you just stick all the liquid in at once?

[MamaChocoholic]

I want to make risotto. I have two 11 month old babies and cannot stand there ladling for 20 minutes. if I stick all the liquid in at once, and pop back and check it every so often, surely it will turn out about the same? anyone with experience of a lazy risotto?

I don't know but now I have tortured myself by reading through all the recipes and I really really want Risotto now. Stupid bloody Dukan diet
