Nurseries not shut? Covid

With tonight’s lockdown, nurseries and playgrounds will remain open amidst the national lockdown.

I am pregnant, and my son is in nursery.

Do you think it wise to pull him out for my own health and safety?

I am not high risk due to any other reasons, only moderate risk due to being pregnant. But I don’t want to risk getting covid

I will soon be in my third trimester. Not sure what to do.
