For the third time in the past 2 weeks (at daycare) little miss R has decided she can't stand to have poop in her diaper for more than a minute....so she puts her hand down the back in an effort to get it off

Is there anything I can do to stop this behavior? Obviously the ladies at daycare are trying to be acutely aware of when she goes to the bathroom but she poops 3 times a day at daycare.

For now, she's back to onesies so she can't get in there!
