Just start. Do it. There is soooo much you could learn and read and do, you could spend years trying to figure it all out and another few years getting organized.
Start simple, and add more as you get more comfortable, learn more, and see the reaction from your baby.
Pick one idea (reading or math or swimming or music or whatever interests your/your baby). Next pick one or two activities (flashcards or LR or Music lessons or whatever) and do that activity every day, maybe 2 or 3 or 4 times a day. Start with this tomorrow.
I feel it is more important to start now with an imperfect system, then to start 6 months from now with a perfect (is that even possible?) system.
Remember Doman says something to the tune of " Learning is a game you will win no matter how poorly you play it"
