I agree with limewave here...seems like another year or two will give them ample time to grow into that age where they should start doing things themselves (morning routines like channlluv said)
That being said, it does not mean you have to bag your training just don't feel the need to stick to a rigid schedule until your kids are more independent.
Another note, I used to lap swim at a pool that would rope off half the pool for lessons and the other half for lap-swim. Maybe your area might offer something similar? Also, our YMCA has a great summer kids camp that the kids are in, giving you a few hours to train in the pool, treadmill (dreadmill in my mind, but if it is all you have!) and/or spinning classes! This would keep you in great shape and "train-ready" when the time comes you can devote yourself to a schedule...
my $0.02...Good Luck and don't stop getting out there when you can!!!
