We have tiles in one of our lounge areas and carpet in the other. The one that is tiled has a huge mat and also has the gas wall heater's main vent. So it is pretty warm! There is another small vent that ducts into the carpeted lounge.

Clothes wise, DS wears a snappy crotch singlet to bed as well as socks and long sleeved pjs. He has a winter bag with no blankets. We keep his door shut to help keep heat in. When he was newborn we kept the heater on all night as he was born in winter but we don't now he is older.

We've recently had ducted reverse cycle heating and cooling put in, mainly for airconditioning. But today I switched the heat on for 5 mins to warm up the tiles and it did a great job!
