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.

Vitamins and supplements also ill make sure to wash all bedsheets and everything else often. At lease once a week. Airing the room and letting it ventilate will also be helpful. Otherwise someone may have to sleep in the living room.
