He is really cute! Go for it with the EC! I didn't find out about it until DS was 8 months, so we got something similar to the little baby bjorn squatty potty (not sure of it's official name) and just started catching morning pees. Before he learned to walk we never missed a morning pee. I figure if nothing else we saved on washing a few diapers. My understanding is the earlier you start (so you are in great shape) the better your chance of success. Good luck!
I agree... earlier is better. My parents started ec'ing dd when she was 8 months old. I didn't practice it but I have recently started to. I really like it. In fact I am looking toward a diaperfree day, a day I thought would never come.
