Making First Friends

Keep Playdates Short

Limit playdates for preschoolers to about two hours -- and fill your guests in on the time frame beforehand. After that, kids start to lose interest. "Think about it: Once you spend a couple of hours with someone, you're usually ready to move on too," says Dr. Weinraub. "Rather than burning out on each other, you want the kids to look forward to getting together in the future."
