Hello.
From your post, I think you would benefit from sleep training your LO so that you don't have to do the accidental parenting. In the long run, the accidental parenting will probably take up more of your time. Take a look at the sleep boards for nap, etc. there is loads of GREAT advice there
You seem to have a good handle so far on EASY.
As far as the 2yr old goes, try to incorporate him in with the training, that way your ds will be used to him being there
It can be quite overwhelming at times, I know. Just keep EASY in mind, try to relax and go with the flow. If your ds naps in the car every afternoon when you pick your toddler up from school, then that's OK. - it becomes part of his routine

...wanted to add too, if you don't have Tracy's 3rd book, I highly recommend it. It answers a lot of why/what/how...
