how much change you change a child's personality?

DS can be very sweet and polite sometimes, but he can take a bit of time to get warmed up to new kids and it not always flexible when it comes to changing routine or having things not go his way. I'm trying to decide if he is just a toddler on a phase or if he'll start warming up faster - he's not shy, but he'll say no and be VERY protective of his things (toys and even things like songs and tv shows)

Sounds very similar to K.  I think it has something to do with the transition at this age from solo play to group play.  Their little brains are trying to figure out how to set boundaries, make friends, and not lose "their" things. 

Knowing that K was going to be an only child I've always gone out of my way to try to socialize her and keep her routine changed up.  I can't stand the idea of having one of the spoiled, only child, it's my way or the highway, non sharing, kids. 

Maybe a play group or some class of some kind might help.
