Kids this age are learning that they have some power in the world, and they'll seize any opportunity to use it. So don't be surprised if your mini Trump says just about anything to stall his bedtime -- even if he's about to fall asleep mid-sentence.
Rest easier by... making small tweaks to your child's bedtime routine. You should still stick to the basics -- a bath, a story, some cuddling, then lights-out -- but let him make small decisions along the way, suggests Jill Spivack, cocreator of the book and DVD The Sleepeasy Solution. Your toddler may be less likely to balk at bedtime if he gets to call a few of the shots. (Red or yellow pj's? Three good-night kisses or four?)
If he cries when you leave his room, explain that it's time to sleep and say that you'll be back to check on him when he's calm, says Brett Kuhn, PhD, a licensed psychologist at the University of Nebraska Medical Center and Children's Sleep Center, in Omaha. Return, as promised, but don't stick around. Or try mom Gina Beltrami's clever sleep strategy: After she tucked in her toddler, Sonny, she set a timer for five minutes.
