I'm in the middle of that myself! Backing off has been a big help. My baby is 16 months old, so a little bit older. I have talked to her like the above posters have suggested. In fact just last week (with some awesome insight from our very own Carlyle) I backed way way off. That meant that most of last week was soaked diapers and poopy pants (nothing new there, lots of poop misses the last few months) and now she is initiating things more. I even didn't take her potty first thing in the morning for a few days and didn't take off her diaper until she told me she wanted to. Totally a different approach from what I'd been doing before, but it sure seems to me that EC at this age is different from what it is when they are infants.
I put training pants on her when we're doing back-up, because they can be put on standing up. She's mostly ok with that.
She can also say "no" now, so if we're heading to the potty and she says no, then that's it, I don't put her on the potty. I don't distract her with a toy or anything, I just don't put her on. That, too, is different from where we were previously. I also offer way less frequently than before. I do still offer, just not as often.
I wish I had backed off like this sooner, but I didn't!
I read about babies that take themselves to the potty as young as this or younger, my babe has only kind of done that one time. (And it was last week after I backed off, she took herself outside when I left the door open.)
My dd (and your baby, too!!!) is learning to do lots of things on her own right now. She's really into spoons, and prefers spoon foods to the finger foods I'd been giving her. Going potty on her own is another thing she's learning, and it's messy, too!
We've had lots of no-catch or one-catch days, and also lately we've had a few one-miss days sprinkled in there! Last week we had a one-miss day, then a molar started busting through. That was the end of that. I'm happy to say that yesterday was a zero-miss day. And we had two days of pooping in the potty. This is big for us!!!!
I had been comparing my baby to what she was before (no poop misses at all from 8-10 months of age, not one) and to other babies (I met a lady who was buying a potty for her 14 month old who suddenly didn't like to poop her pants. But my baby was EC'd and she didn't seem to mind pooping her pants!) And I had to stop doing that, because she's the baby she is right now! It helped me!
Despite the many misses, it really does seem like it's coming together.
I could go on and on, but I'll stop right now.
