Time to Potty Train?

Sunday when D went to pick up M from the nursery at church this exchange occurred

Teacher: M went peepee and poop in the potty today!!!
D: (gives teacher a questioning look) M?
Teacher: You are potty training him right?
D: No.
Teacher: Well he told us he had to go and we took him and he went perfectly.
D: I guess it's time to start potty training.

So there you have it. We are now attempting more potty training with M. He was going once in a while before just for fun, but now we are going to give it a shot (though not with big boy underwear or anything) A friend at the bus stop has a little one a bit older who has just done the same kind of thing so we talked this morning about splitting Costco packs of diapers until we figure out if this potty thing is going to take. I really hate to get 30 diapers into a 110 pack and not need them.
love and hugs and bundle up--- tonight is supposed to be the first snowfall of the year in the Cascades and we are getting our second minor wind storm,
