No more diapers for Sabrina

While Sabrina has been potty trained during the day since Febuary, she decided a few nights ago that she did not want to wear diapers at night anymore.  No pullups, no diapers, just big girl underwear (and jammies, obviously).  So okay!  I've been prepared for this; a while ago I bought two water-proof fitted sheet protectors.  So on her bed is a sheet protector, fitted sheet, sheet protector, fitted sheet.  The idea being that if she woke up in the middle of the night because she wet the bed, we could just strip off the first fitted sheet and sheet protector and she could go back to sleep.  We put her potty in her room and said if you need to use the potty here it is and that's that.  The first two nights her pants were wet but the sheets were dry. We think that she tried to use the potty when she got up but maybe had trouble with her pajamas.  However last night her sheets were wet.  Did she just wet the bed?  Did she wet the bed while she was sleeping and is such a heavy sleeper she never noticed?  I have no idea.  If this continues I think we will have to wake her up before we go to sleep and make her go to the bathroom.  But I'm really proud that she decided on her own that she wasn't going to wear diapers at night any longer.  you go,  (big) girl!
