organization and time management

with the addition of a fourth child, man, this time management thing is more important than ever. it seems like i'm just grabbing time here and there whenever its available to try to get work done. many times i feel like i'm spinning my wheels and not being productive at all! i need to make out a schedule for myself and the kids, they say kids like schedules, right? i need to learn to type on handed too - cause i have to do it at least a few times a day. anyone have any tips??
