“I want a sleepover at Hayley’s house,” your 6-year-old suddenly asserts. Can she handle it, or will you get the 2 a.m. come-get-me call? Children are prepared for sleepovers at varying ages, says parenting expert Susan Newman, PhD. So before you say yes, figure out your child’s readiness. Has she ever stayed the night with a cousin, aunt or grandparent? She should feel comfortable sleeping in a new environment. How much sleep does she need to function well? Are there bed-wetting problems? Share concerns with the host parent, as well as things like your child’s need for a night-light and her aversion to scary movies. Also assess the host’s home. You should know the parents and their household. Is it clean? Are there alcohol issues? If you have any reservations about safety, say no. “Go with your gut,” advises Dr. Newman. If your child seems ready and you’re comfortable, success is a snooze away.
