I've been doing this as I work with so many children daily and deal with a lot of parents and I really don't want to get it or pass it on to my children
(my youngest is 3 soon and it's scary enough, so having a newborn with this going on must be worrying, stay strong Mama) My husband and I take off our jackets and shoes in the porch, come in wash hands and go and change, clothes straight in the washing bag.
Maybe your hubby could start wearing gloves in work if there are not any measures in place already. Just make sure he is washing his hands before coming into contact with you and baby.
At the nursery we have started with every child/parent coming in washing hands before entering our rooms and we have a germ station where we have the children washing hands more times throughout their session, not just after the toilet and at snack time.
