We now need to teach table manners too

[Strictly1]

From the DfE today:

Once the pandemic is over, I would encourage you to consider introducing measures such as ‘family dining’ which can help instil good eating habits, if facilities allow.
We don't have the time to do everything.

I am a TA and have worked in various year groups. It's pretty normal for me to have to teach children how to use a knife and fork. Many children do not use them at home, instead they use their fingers or just a fork whilst eating in front of the TV. Food at home is often things like chips and nuggets.
