Parents living in a small flat eg 1-2 room rental flat with no help at all. How do you prevent your children from catching the bug when they share the same room and same bed? I am sharing a queen size bed with my 3 girls below 5yo.

Tough. Not about the size of ur flat really but because there will be a lot of close contact among u all day in day out. They are minimum is good hygiene (keep washing hands), mask up, multivitamin, lots of water and ventilation, lots of rest - tired bodies are more prone to catching the bug too. Get well soon
