Ive mentioned a couple things to my husband and he's given me the 'that's a bit over the top they need to be exposed to germs'.
All I've mentioned is that we should get back into the habit of washing our hands when we come in from being out be it shopping or whatever and when stepdaughter comes in from secondary school. Also that I don't want anyone coming over if they have a cough or sniffle let alone a full blown cold.
Depending on when he arrives baby will be having first vaccines just before or after Xmas
