Hi, S.. Well, instead of throwing out good underwear, why not send her to daycare in those PullUps? If they're going to throw away her panties when she poops in them, they shouldn't object to throwing away PullUps. In the event that she overcomes whatever disturbs her about pooping in the potty, she can pull them down, do her thing, and pull them back up -- that's why they're called PullUps. I wish to God they were around when my son was little!
And why is it that daycare gets to dictate to you when she's ready to leave diapers behind? If you're paying them to watch your child, then they need to be more flexible.
I know PullUps cost a bit, but they're probably cheaper than replacing a pair of underwear each day. She's not ready to poop in the toilet for some reason -- maybe she doesn't want to do it in front of other kids or even other adults?? I know everyone is probably sick of me saying this, but when a kid is scared of pooping in the potty, one way to ease that fear is to demonstrate how nice it is to poop in the potty.
That's right -- let her see you going to the toilet, sitting down like a good girl, and letting it go where it can't hurt anything. Tell her how good it feels to not have poop touch your buttocks (or whatever word you use for buttcheeks). Then nobody has to touch it, etc., and no one has to get dirty cleaning it out of the underwear. You can even let her flush for you.
At her age, she is finding it important to be a girl and to copy what you do as her main role model of how to be a female. If you stress to her that it feels good to be a girl and go poopy in the toilet, this will give her more incentive.
Another factor to consider is that #1 -- she's not capable of warning you in time, because she's just over 2 years old and has no sense of time. All time is now; she knows she's going when she starts to go. She probably can't help herself. #2 -- she gets a little bit extra attention for pooping in her pants, even if it's negative attention. Again, ppl are probably sick of me saying this, too, but try making sure she gets extra attention for other things at other times, and this may ease her craving to get attention for pooping in her pants.
Even though she's proud of being a big girl, she also is missing out on the baby nurturing she has to give up in order to be a big girl. This is one way that little kids compromise -- 90% of the time, they're big girls or big boys, but they cling to that one part of baby-nurturing for a bit longer. They need to see that it's worth their effort to leave the pooping problem behind and be a bigger kid. I'm sure it's different for every child, but I think that paying more attention to her about other things can help diminish the need to be nurtured by having her bottom wiped.
I hope this all works out to everyone's benefit and happiness.
Peace,
Syl
