This big guy is all about order. OCD much? I canNOT tell you how many people say to us, "I bet he'll be an engineer"... If a drawer is left open, he closes it; he puts lids back on everything, has to have his particular 2 blankies on him every sleep, has to have most toys put away in his room before he can fall asleep, it goes on and on... If he has something to stack or line-up, he does it. I'm sure most 2 year olds go through this stage but, I don't remember Lai being quite so orderly with EVERYthing.
