My 22-month-old has recently taken to assigning ownership to everything. She'll grab whatever she sees laying around - books, clothing, whatever - declare whose it is ("it's daddy's", "it's mommy's"), and then insist on giving it to that person (even if the person is not present). She doesn't seem to understand that the owner of an object may want the object to stay where it is. :)
This is out of curiosity and not worry, but do most kids go through a phase like this? I'm trying to figure out if it's widespread, or if it's just her nature (there's a pretty strong "meticulous" streak in my family).
