Neither of our boys have ever been really attached to a blanky or a stuffed animal or anything really. Until now. Luckily, it's an attachment that's easily replaced, cleaned and switched out. Noah's obsessed with socks.
Daycare told us that he's always taking his socks and crawling around with them - all day. They also told me that if one of the other kids takes their socks off they always find them with Noah. Creepy, right? Yes is the answer you're looking for. I know. (shame) Fortunately for all of us, he doesn't scream until he has them - he just loves toting them around everywhere. They are great for distraction too.
We noticed it at home too and just kinda laughed at it. Then I noticed when I was looking through pics of the last couple weeks that I have a LOT with Noah and his security socks.
you can't see it really well, but he's holding onto a red sock here

I guess it could be worse, but it's just so funny. He doesn't care about color or size. He will find a sock in a pile of laundry and he literally carries it around with him everywhere. He'll crawl around and play for hours holding onto one (or two if he's lucky) socks. I love my weird kid.
