I sometimes come across very short answers and since I didn't find a meta discussion about it, here we go.
This question is about a 5 year-old child, who was locked into the bathroom by their teacher. This is one of the answers it received:
Effects of locking your child in the bathroom: Fear, anxiety, trauma and isolation.
This one already got an upvote.
Could it be possible to limit car usage with child to barest minimum? Like going on foot or using public transports?
One of the answers reads
Everything you're doing sounds perfectly fine. At that age angry outbursts are normal. Just be patient and in time they should subside.
The first example is really short and not backed up. The second one is more of a Try this approach. The third is the longest one (three whole sentences), but still very short. But they represent the spectrum of answers I want to discuss.
I have been active in another also somewhat more subjective SE site (IPS)*, so it made me wonder a bit that answers wouldn't be expected to be backed up (with either explanations, experiences, sources or a combination of them). Usually, answers are and there are plenty of excellent ones, so my surprise was even bigger.
I noticed that the Help Center says
Brevity is acceptable, but fuller explanations are better.
But when is short too short?
Are one-line answers acceptable on Parenting.SE?
(And if not, then what to do about them?)
*I'm not in any way trying to say that IPS compared favorably to Parenting. That's just to explain where I'm coming from and why I ask this question.
