There are a lot of non-alcoholics whose social life does not focus on alcohol. You just did not choose them as friends in the past.
In future, as you move on in sobriety, you can expand your social circle so that you can be around moms' who do not have alcohol in sippy cups. (That one really got me. What kind of mothers are these?) Just be patient and willing to meet new folk/try new things. It really can happen.
