Can I take my toddler into the delivery ward with me? Should I have my husband stay home with him?

I had planned to have my sister look after him during labour...but there’s a confirmed case of Coronavirus at her kids’ school (all 3 of her kids attend the same school) and now I don’t want my toddler to be with her family in case he catches something and passes it onto the newborn.

Due date is 4 days away and I’m freaking out more about this than I have anything else during the pregnancy. Not worried at all about the birth, just the care of my toddler!

Advice? Clearly paranoid mother here 🤦‍♀️
