I do not want
One children willingly play in an arena till one and a half years, and others in months consider an arena as prison.
Most of children with pleasure play in an arena, will not learn to go yet, i.
e.
approximately till months.
I would advise to let out the child from an arena when to it it becomes uninteresting there.
I do not want to tell that it should be let out as soon as he begins to whimper.
If you give to the child something new and interesting, he can cheerfully play an hour more in an arena.
