It's Easy to Escape a Big-Kid Bed
Rest easier by... carrying your midnight wanderer back to her room every time she busts into yours. If you let her crash with you, you're setting the stage for a never-ending bedtime battle. Consider hanging bells on your doorknob so you can hear your toddler coming; that way, you can walk her back to her room before she climbs into your bed and makes herself comfy.
Another way to avoid sleepless nights is to install a baby gate on your child's door. "Explain that it's there to keep her safe, since she could get hurt walking around the house by herself in the dark," says Spivack. Leave her bedroom door open so she doesn't feel alone.
