Lately I have been having a problem keeping Camryn in her pajamas while she is in her crib. She loves to take them off along with her diaper. I had had enough of cleaning up after her so I ordered these pajamas that do up in the back yesterday. My mom's neighbor's son invented these particular pajamas. You can buy them at http://www.littlekeepersleeper.com. I can't wait until they get here.
