I first noticed it earlier this week when he latched on to Bess's neck. Then, he did it to me, and now, it's become the norm. I may be overstating it, but from where I sit, being on the receiving end of one of Freddie's hugs is very possibly the greatest feeling in the history of feelings.
Try it; you'll like it.
(UPDATE: I have asked Freddie to hug me about 9,000 times today. Now, when he does it, he'll sometimes squeeze like a bear hug. Other times, he'll make a grunt while he squeezes. Seriously. Freddie's hugs are the best things, since Qdoba's BOGO burritos.)
