My youngest was potty trained for poo completely by 9 months.  In China they have to potty train the babies early because diapers are expensive to wash and only the well off buy disposables.  So they put the babies in pants with a split so they can pee and poo while you hold them over a potty or where ever.  Totally green and cheaper.  I saw women holding tiny babies over gutters to pee while walking down the street.  It was so nice to not have to deal with poo diapers!  I did let her continue to use diapers for pee though but that was only 4 a day usually since she peed when she pooped on the potty too.  YOu can do it.  Put them on the potty first thing in the am and give them the signal.  I used to say "Ba!" and pretend to grunt a bit at first.  Then after awhile she just knew when she sat on the potty to poo.  Put him there after every meal and after a warm bath too.  They always seem to poo after th bath rather than before.
