Even the most amicable split is world-changing for young children. Here are a few key tips for grown-ups trying to help their kids navigate this big transition. - Give children as much heads-up as you can — as soon as you've made a definite decision to split up.- It's a grown-up problem. Don't share details that will confuse your child or hurt your partner.- Don't fear the big feelings or the "pajama truth-bomb." - It's good for kids to talk about a separation — even when it may be painful for adults to hear.- Make sure your kids know that not everything will change. - Keep routines, and toys, consistent, even if they're traveling from one home to another. - Look back together on the good memories.
