Last night, Randy & I were trying to catch up on some work stuff before the kid's bedtime routine (which meant we were both at our computers in the office). Morgan walked in (at least twice) and said "Daddy I have to potty". He finally said, "Honey, not tonight".
Now, keep in mind, usually the potty routine consists of stripping the kid, sitting for 5 second, and repeating that about 30 times in 5 minutes. Rarely did any "potty" make it in the potty.
A few mintues later, I walk into the living room - Morgan is sitting on her potty, pants around her ankles, and diaper flung onto the nearby couch. So, I sit down by her, and she stands up - SUCCESS!
Maybe she just doesn't like having someone watch her when she goes to the bathroom...
