But to suggest keeping a child from either one of their parents for months on end is absurd. If you're being that strict, then people should be banned from shopping and we should all have rations dropped at our door.
It'd help if you didn't allege things others haven't said. C R didn't say months. If people keep on adding bits on then everyone in society is going to be falling out with everyone else and you will be so jumpy you will be falling out with everyone in your life and have a miserable time.
The original lockdown was for three weeks. One of the things that will have been taken into account is the mixed messages from having a 3 week break and then relaxing and reapplying. Or taking it away later. From the behaviour point of view it's probably why the government probably clarified that the exeption was permanent.
