Is it abusive...

We gate our two girls up in their room at night.  Our older dd sleepwalks, and I don't want her getting into anything dangerous.  I need to hear them, so we got a baby gate that can go in their doorway that she is not able to push down without making A LOT of noise.  Not abuse, smart parenting.

I put a gate in my 3 years olds door at night. I don't think it's abusive at all. Just safe parenting. Just keeping ur kid out of anything dangerous

Keeping a child safe is never abuse, imo.

Locking your child in their room? I worry about safety if there is a fire it's harder to get them out. Gates worked for us.

Not at all! I have a door knob cover on the inside of my son's bedroom door so he cant open it. I keep a monitor in there so i can hear when he wakes up.

I have a door knob cover in my sons room. He will get out and get into the kitchen open the doors to the house

I feel awful about it lol. We have had this issue with her wondering the house for about a year now and hubby got fed up about an hour ago when he woke with her in our bathroom playing with his razor, so he just went and turned her door knob around so that the lock-turn is on the outside and locked her in there. 

She isn't crying or anything, but every few minuets I can hear her try the knob... I think I'm going to pick up a baby gate tomorrow, I don't like her door being closed, much less locked.

I think that it's sending the wrong message by telling the toddler that you expect for him/her to misbehave.  You should try to get up periodically to check on him/her instead of locking them in their room.  It can cause children to have accidents and other health problems.

Absolutely. Not only is it abusive (neglect) it is a giant fucking fire hazard and beyond irresponsible and dangerous.

Baby gate! :)
