Honestly, we have done better limiting time around kids and moms who are not supportive. My kid is an extrovert and when there is a good match I let him fly, but he picked up very early that he was different and negative people made a very strong impression.
Think about the behavior you are modeling. If you two are happy and blossoming at home, stick with it and if you find some nice kids at the library, pursue playdates. These kids tend to take one repetition to learn a fact when some other kids take thirty... If she thinks you are embarrassed by her learning, it will stick long before school starts...
You might think about something structured and safe like parent tot gymnastics. It is fantastic for developing confidence with the right coach.
Just my two cents...
What area of the country are you in? Maybe there are some activities or groups we can point you toward...
