J.B.
Hi J., we moved my daughter into a big girl bed at her 2 year birthday out of necessity, not because we wanted to. Because of her young age, she was constantly coming out of her room the entire night. My method of resolving that might not be considered conventional, but it worked for us. We just put the door knob handle thingies on her door so she couldn't get out. She takes awhile to fall asleep, also, and would go and bother her older brother if she wanted to play. I still leave a monitor in her bedroom so I can hear if she needs me. It's funny because in the mornings, she'll turn off her nightlight and her fan and then knock on the door when she's ready to come out. It has saved me a lot of worry at night wondering what she might get into and we all get more sleep. I've also heard of parents turning the door knobs around so the lock is on the outside. Just make sure you keep a key on the inside door ledge so you don't get inadvertantly locked in! A baby gate would not have worked for us as my daughter is a climber and would just climb right over it. Try whatever works for you and your family. Good luck to you!
