My cat won't leave me alone.

We have two cats and the older one who was always very skittish and didn't like to be touched much has suddenly become my best friend. As soon as I get home he has to be laying next to me, sometimes on me. He follows me to the bathroom. He lays in the bathroom doorway when I'm showering. When I'm sitting or laying down he is always trying to lick my hands and nuzzel whatever I'm holding. I'm about 24 weeks now and this extra cuddly behavior has been increasing since I got pregnant. I wonder what he will think of our baby girl :). Anyone else have this going on with their furry friend?
