With Rizzo, boy 7.5 months old, he is a total lover. He runs and plays and is always excited about anything that I'm doing if I address him and make sure he feels like he is involved :P He loves to cuddle on the couch when I'm watching a movie, but as soon as I move it is play time
I don't have a little girl, but my Rizzo is definatly affectionate and though it usually takes a couple hours around someone before he is ready to play or cuddle with new person.
