I guess my biggest concern is that if we just 'go with it' for now we wont ever get EASY implemented.
Throw that idea out the window, hun.
You need to just 'go with it' for now, but you might be surprised how quickly 'it' can change. By the end of the second week, he'll be different already. So he needs to feed frequently right now to build supply and to grow. But this is not forever! By the time he gets to six weeks, it'll be a totally different ball game.
And with a 19 mo in the mix, honestly, I think most of us here with a toddler and a newborn didn't really think too much about EASY til about 3 mos or so. what I'm trying to say is that you can keep routine in mind, you can gently move things routine-wards, but you need to be flexible with it, and with yourself. Make BW work for you, and not the other way round.
if you've BFing questions, and aren't getting good support, our own BF board is great. I also highly recommend looking at Jack Newman's website. It has BFing videos that are just brilliant, shows every step and explain very well.
