Am I crazy? Or is that almost abusive?

If your 4 year old is struggling to sleep in their own bed, what do you do to break that?? How do you go about getting them to sleep in their own bed?? Any advice is appreciated.

Also, do you all think it’s OK to lock a 4 year old in their bedroom at night so they can’t get out??
How about taking away all their clothes so they are too cold to get back out of the bad???

I have had a horrible argument with someone who thinks these things are ok. And when discussed with a few other people, they ALSO seemed to think those things were OK.

Am I crazy??? Or is that almost child abuse???

Please let me know, thank you
