Most team sports don't start until about age 5. Some kids are ready before this, but some not until 7 or later. Larger towns and cities often have programs for pre-K kids. These are rarely team oriented, and are more skill/fun based. Student/instructor ratios vary from 1:1 to usually no more than 1:5 and they are pure fun. Community education, YMCA, parks, churches and various other entities offer year round activities for little ones. If you'd like assistance tracking down a program, post back with which country and city you are in.
