My boys (3 and 1) often give each other hug and smooches. They make the smooching noise without actually kissing each other. We do it every night as we walk out of their room and they have both picked up on it and do it during the day.
Just now, Sage and Kolby were hugging and Sage said "Love you." Smooch. Bo said, "Yove you." Smooch
That totally made up for the rough couple of mornings we have had around here!
And instead of running for my camara to catch a video, I reached for my laptop to blog it!
