Dominoes, potty seat, naptime and Kendall's room

Sorry for the crazy title, but this post is just filled with a lot of random stuff that I couldn't seem to pull together. Read on and you'll see what I mean.Question: Is there a developmental "phase" that I am unaware of in which kids keep oddly busy by lining things up, or is my child just showing early signs of OCD? Don't get me wrong, I am thoroughly enjoying Avery's new way of playing because it keeps her occupied so I can get more things done, but it just seems a little strange. I was getting ready for game night at church tonight and so I opened up the dominoes for her to play with while I made her dinner, packed the bag, etc. Probably 10 or 15 minutes later she says, "Look, I make my dominoes," and this is what I found. Maybe she's just destined to be the kid at school with the most organized desk, locker, etc.

She has done 2 other new things lately as well. One is that she tinkled and pooped in the potty today, and the other is falling asleep by herself (no patting!) at naptime. She has been showing a lot of interest and curiosity about going to the potty, so several weeks ago we bought her a potty seat, just to try it out. Honestly, I really don't want to deal with the whole potty training thing until Kendall is a couple months old, but it just didn't seem right to tell Avery "No" when she asks to go in the potty. When we first bought the seat, we tried it out for the weekend, but she just didn't quite grasp the whole concept even though she did go tinkle twice in the potty. But today she asked to go poo-poo in the potty, so I got the seat back out. I sat there with her for a little while and what do you know? She may be forcing me to potty train her despite my previous plan! I guess I'll just "go with the flow" and see what happens. And her falling asleep by herself at naptime could not come at a better time! I have been worrying about how in the world I'm going to pat her to sleep at naptime with Kendall around. She has been falling asleep on her own at night since she was little, but naptime has always been a different story. In the beginning it was bouncing in my arms or the bouncy seat, then we changed to rocking, then patting, and now she is FINALLY to a point where she won't cry when I leave the room and will just lay there playing and talking for 20-30 minutes until she falls asleep. I am just crossing my fingers that Kendall's birth won't disrupt the whole thing and cause her to quit taking a nap altogether or something.

Speaking of Kendall, I included a few pics of her room. The only thing we have left to do is hang her curtain. We used the same nursery bedding, but I did get several new things to hang on the walls. Obviously the "K", which I painted myself, is new, and then one of the signs above the rocker that says "Luv ya to the moon and back" I got at Canton, and then the 2 mirrors on either side of her dresser are new too. All we need now is a baby! Any birth date guesses?
