Children need social interaction as young as age two. Not only does it help them develop social skills; it also enforces their sense of identity as they compare themselves to other kids and families. That’s why it’s at this age that most moms take their kids out to play in the park, or in most societies, arrange play dates with fellow mothers. If you’re both too busy, however, that can be tricky.

The most important thing is to plan it well in advance. Depending on how packed both moms’ schedules are, this can be a week, two weeks, or a month. If it’s your first play date, give yourself enough time to get to know the place and find a good venue. Two-year-olds can be very curious, and you want to make sure you go somewhere with as few hazards as possible.

You may also want to bring toys along. Avoid duplicates by discussing it with your fellow moms, and planning to take toys that work well together. A mix of educational and creative tools, such as books and puzzles, will usually go hand in hand. Also, choose toys that can be shared between the kids—a book that’s big enough for two to read, or a play keyboard with room for two little pairs of hands.

If possible, have the kids meet before the play date. Some children are naturally shy and may spend the whole day tethered to their moms if they’re not familiar with their playmates. If this is the case, you’ll want to stay close to your child, as your presence makes them feel more comfortable. Interact with the other kids so they can take a cue.

Don’t be afraid to widen your kid’s social circle. Two-year-olds and six-year-olds don’t necessarily have to stay apart. While mixing age groups doesn’t always work, it benefits both parties: the younger child learns new words and tricks from the older ones, and the older ones get to “show off” and feel empowered by being able to teach other kids.

Finally, remember to make it a habit, and arrange dates with the same groups as much as possible. It’s important for kids to associate certain activities with each other. It’s what forms their bond and helps them understand the concept of friendship. They’ll also learn things faster as the company makes them more receptive to new ideas, and even encourages them to explore on their own.
