Don't make another problem by failing to fix the first - keep the siblings out. Time for a family meeting to explain the new system of off-limit spaces.

The rule in our house is no one in our bedrooms without permission. Things you don't want touched? Put them in your room because the living room, etc are family spaces. Need some personal space to cool down, be alone, etc? Go to your room. That's not a punishment - it's a refuge, especially for bigger kids who need time away from little ones.

My six year old locks his door to keep out the two years old. He also post a sign saying "3+" like those age markers on toy package.

I don't think it's a problem. The lock is privacy lock so it doesn't require a key, just a pin.

I’m one of the previous posters. Recently one of my kids needed a replacement door knob and I installed this myself. It was really easy and I had never changed a handle before. It has a lock and a way to quickly get in with a screwdriver. I bought one of the cheapest I could find on Amazon. https://www.amazon.com/gp/aw/d/B003F3FBQC?psc=1&ref=ppx_pop_mob_b_asin_title

Do the bathrooms not have locks, either? Everybody should be able to have some space where they have privacy and can feel secure. Get her an interior locking door knob set. It installs in minutes and can be opened from the outside in an emergency. (Just like the bathroom locks.)

Siblings are notorious for violating personal boundaries just to be cruel. Kids (especially girls) should have a feeling of security in their bedrooms and be assured that nobody is going to walk in on them without permission. She should be allowed to have a standard bedroom door lock - the kind that can be unlocked with a screwdriver or "special key" (that looks like a tiny screwdriver).

Kids should not be able to lock doors. They are irrational and will do stupid shit with it.

Door knobs that lock but can be opened with a screwdriver or paperclip are about $10-12 at Home Depot and take about 30 minutes to install. You can get screwdriver-head type keys and put them on the top of the door frame, so the younger kids can't get to it, but the parents can.

Yes, I agree that they should be teaching the younger kids to respect closed doors, but often it takes repetitive teaching to teach and get them to respect the closed door and there can be a lot of emotional fights between siblings that can easily be avoided by just replacing the door knob.

Or just use a bell.

How awful that the 10 year old can’t get a spot away from her siblings, like a bedroom! Parent the younger ones please. They need to stop.
