Sid is a real treat these days!  He's all smiles and giggles when you tickle or kiss his neck.  He's getting really good at tummy time - he can hold his head high and even lifts his butt up in the air as if he's making an attempt to crawl.  If you leave him for a while you'll notice that slowly but surely he'll be moving off of his mat.  He is particularly good at this during the night.  He'll cuddle up to you in bed and continue moving inward until he pushes you off of the bed.  When Sid sleeps in our bed it usually looks something like this:  Sid lying with arms and legs spread out, occupying about 2/3 of the bed and Mom and Dad smashed up on their sides on the other 1/3 of the bed - clinging desperately to the sheets to avoid falling off.
