Zoee's little accident

So we have had a fun few days. Zoee has just been so cute lately. Yesterday was really funny. We were changing her and decided to let her run around without her diaper for a little while to "air out." She loves doing this but I am afraid she will pee or poop on the carpet so it doesn't happen often. I was nervous because for dinner she drank 2 glasses of water and so I was sure she would pee. I thought that she was doing something because she got really quiet for a minute, a pretty good sign that she is into something. She was really quiet so I went to look for her. She was coming out of our bedroom and was trying to shut the door. I looked around but didn't find any pee so I didn't think she had peed. We were surprised but glad. We put a diaper back on and put her to bed. Well, we went to bed later that night. I got ready for bed and was kinda cleaning up the room. I went to put some clothes in the hamper and stepped in something wet on the bathroom floor. It was dark and I couldn't really see so I didn't think anything of it really but then I remembered that she had been so quiet so I turned on the light to look and sure enough...a little puddle of pee. We laughed for a minute and I cleaned it up. I was kinda proud of her because she went into the bathroom to pee and didn't just pee on the carpet. Do you think she knows that we pee in the bathroom? I think she does. I think she is really smart like that.
