Manipulating Daddy

Avery has learned how to manipulate mom and dad with her new rolling-over trick. She is still not able to consistently roll from tummy to back so when she gets on her stomach and gets upset that she is stuck, we help and roll her back over. She did this in her crib last week at 4:00 am so Dad went in to roll her on her back so she could fall asleep again. The second he left the room she did it again and had her head up high and was expectantly waiting for him to come back in. She did it a 3rd time, again, with her head held high looking for Dad to come into the room. Hung realized that he could put her close to the side of the crib on her right side (she can only roll to the right at the moment) and then she couldn't roll over again. She tried for about 5 minutes, realized it wasn't going to work and went back to sleep. We were cracking up!! Those little eyes just staring at the door waiting for us to come "save" her. What are we going to do when we can no longer out-smart her?
