Toddler refuses to sleep, ever. Now cannot even be contained in bedroom. Is locking her in okay?

My 4 year old daughter is horrible at sleeping. She fights it endlessly. For about a year now, we would put her to bed to a routine (first at 7pm and then at 730pm), and then she would sort of play a little until eventually she would fall asleep (anywhere between 730 and 1000pm).Until the last few weeks, we had a childproof thing on her doorknob and it kept her in her room. However, she has solved that Rubik's cube and can now get out any time she wants to. This means, she wants to come out and talk to us about squirrels instead of sleeping. Or how she wants to go at 9pm and skip rocks at the lake 3 hours away. Or remember that time when we had cake? We should do that again, at 830pm.She also has to go to the potty between 3-435 times every night. She knows we will not be as militant if she needs to use the potty, because we certainly don't want to discourage her from using the bathroom instead of her toybox or lower drawers of her dresser when nature calls.She used to have "quiet time" for an hour and a half mid-day, but this was dependent on her being unable to breach the defenses. Now, there is no quiet time. My wife used to rely on this time of day to get some work done (she works from home).So, we laugh, but I know that sleep is critical to neurological development. It is also a crime against nature that someone would not embrace a mandatory mid-day nap, but apparently the UN doesn't have a commission that investigates this so we're okay for the moment.They say (those so called "child experts") that you should calmly escort your child back to her room, tell her you love her, and tell her she has to stay in there. This is about as effective as asking the tide to stop coming up so far on the beach, please, over and over again.I have contemplated turning her doorknob around so that I can lock it from the outside. I have contemplated latching it with a screen-door latch.We watch her on a video monitor (so we can document her non-sleeping shenanigans for our upcoming documentary SLEEP IS FOR THE WEAK).What did you do? via /r/Parenting https://ift.tt/2HS5JUi
