How in the hell do you get a child to stay in their room at night?

Our 4yo has her bedroom on the second floor and we're on the first floor. We had been having her door closed with a child proof thing on it and utilized a video monitor. So if she ever needed anything, she could just call us. She wasn't really coordinated enough for us to feel like she could navigate down a hallway and staircase in the dark in the middle of the night.Well, she's older, and we're trying to leave her door open at night. (Btw she doesn't need that to get to a potty or get water, she had a bathroom in her bedroom.) Nope! Every night in the middle of the night and also when she wakes up before her Time To Wake clock goes off, she turns on her lights, gets out of bed, goes running through the house, looks for the cats, plays with toys, etc. Not only does this wake us up, but she gets to be a real grouch when she doesn't sleep well. She rarely gets up very early when her door is closed, and when she does, she'll lay in bed and play with the little stuffed animal she sleeps with until it's time to get up.She knows it's wrong, she just doesn't care. She is very hyper (always hopping or spinning or anything while standing, just will not stay still) and it does take awhile for us to get her to bed. We can't keep her in there forever. But every night when we tell her to get back in bed, it's a bit of a tantrum, she says she won't do it again, we'll take privileges away, etc, but then the next night, same. Exact. Thing.I'm sure I may be doing something wrong. Or that she's a 4yo and it's just a phase we'll have to live through for a bit until she actually gets the hang of staying in her room. Can I ask for some advice as to what has worked for you all? Any bit would help. Thank you!! via /r/Parenting http://ift.tt/2AucwSM
