In Scotland we are not allowed in each other’s houses at all.
Our first minister has concerns that this is one of the things that could increase the spread of the virus, especially as people can have it with no symptoms so they/you don’t know they have it.
I appreciate that’s not a rule for many other places and am just mentioning as there is science behind her decision.
I think under the circumstances the church baptism only would be the way to go.
If it were me I’d only have those who absolutely have to attend to be present, like the parents and god parents. Just so the ceremony can be done and the baby welcomed into the church.
Would you be allowed to reaffirm the baptism (ie have it redone whatever that’s called) at a later date so you can all be present say next year when you could have a lovely time together, hugging each other and being happy together afterwards on a sunny day with no worries about distancing or disinfecting your bathroom after someone has used it etc?
When these threads come up I always think imagine how you would feel if granny caught covid and it was traced back to this event, to which you knew you’d broken the rules that are meant to keep us safe. You’d blame yourself and feel awful. COVID still kills. My colleague died of it.
This virus won’t last forever. We can party like it’s 1999 once it’s gone.
