Potty Training

I know that awhile back (last Feb.) I talked about potty training with L. Well, it looks like we are finally getting there. He is great about peeing in the potty, and wearing big boy underpants now. But the problem is that he still poops in his pants. Doesn't matter what we do, he still does it. But the plus is that now D is potty training also. I have a feeling that in a matter of months, both of my children will be potty trained. L even went shopping with my mom and I all day on Friday in his big boy underpants with no accidents. We are all very proud of him, but if you have any suggestions on how to correct the problem we are having, please let me know. Thanks!
