My breeder told me to do one certain thing for sure when I got Kalina and that was to introduce her to as many people as possible the first few weeks I had her.  She said to set my goal at 100 people and, if I truly trusted them, to hand Kalina to them.  Well, it was nice weather and I was able to do that.  As a result, she loves everyone and will let anyone near her.  I think holding your baby alot is fine, but don't keep him from other people.  He needs to be socialized if you want him to be well adjusted.  That's just MHO.  It worked for me.
