Wheeeeeee Meg! Cloth nappies are awesome (As Maz and Anna will testify...you still using cloth Annat? Who have I forgotten?).
It shouldn't be toooo hard to bring Tim over to the dark side. The more kids you have, the more money you'll save. And I don't find them hard to use, depends on what type you decide to get. Maybe start off with some MagicAlls (from babybeehinds, au site). They work like a disposable. If he's a big wee-er you can buy 'boost its' to make the nappy more absorbent. They're pretty darned easy. Pop into the cloth nappy section if you need more help.
