A carpet is good insulation and makes the room cosy but know that carpets need frequent cleaning not from the toys but from dust. Asthma may be an issue for deciding on carpets but today there are asthma friendly materials. Try not to use strong scents for insect tablets unless you ensure ventilation. Freshen the air after kids wake up. Do not use sprays before sleeping time. However mild eucalyptus scent from an electric tablet/jar dispenser is a very good for colds. Kids artifacts? Their favourite toys. Teenage kids? While it's probably totally out of your control, let them experiment with style with their own taste.
