Our little people person

Our little boy just loves to be around people.  If one of us goes into another room he will crawl after us as fast as he can.  He hates to be left alone, and just wants to be around people (preferably being held!) all the time.  In the mornings when he is up before Holly (which is all the time), when she starts to make noise, he's always the first one to notice, and crawls up to her door and starts banging on it.  We've recently started to open the door a tiny bit (without Holly seeing) so Zac can push the door open and crawl in.  It's so cute seeing their reactions!  Holly is so delighted to see him, and excitedly tells me "Zaccy opened my door" when I go in.  Zac of course is thrilled to see his big sister, and grins and giggles.
