DD (2) has been taking off her footie PJs and diaper in the morning as soon as she wakes up before calling out for me. I don't mind since she's day trained and won't pee in the bed, plus it's adorable. A few nights ago I check on her monitor at 8pm and she's sleeping naked!! I snuck a pull up on her and turned up the temp in her room but otherwise left her alone. I've been putting her in a onesie to sleep since in case she does this again. Did your LO go through a naked phase??
