Interested to know what sort of temp you keep your house / living room?
My baby is 10 months now, so not little-little but our house is cold. Its rented so the front door is knackered and drafty and for some reason someone thought it was a good idea to have single glazed french doors in the living room. I'd say at the moment the temp in here is about 17degrees, its 19degrees in his bedroom.
I have the heating on for 3 hours a day, between 6.30-8am and then again 5.30-7pm and it gets a fair bit warmer then but inbetween I'm trying not to heat the whole house unless I need to, just worry about him being cold!
