When it comes to summer, twins have more fun. Here are some outdoor and indoor summer activities especially suited to twins—there's something for every age here.
Teeter-totters and Swings
These playground stand-bys are even more fun for twins, because there is a built-in partner for the teeter-totter, and because they can take turns pushing each other on the swing. Of course, parental intervention may be necessary to encourage twins to actually cooperate, but unlike many singletons, twins usually already see the pros and cons to helping each other have fun.
