I'm finding this weather really hard to figure out! One minute it's still too warm and sunny, even for a jumper, and then the next minute it's really chilly! I went out in flip flops last week!
We've had the heating on for an hour or so in the evenings twice now. Once the sun sets for the day, it's getting a bit cold. DD's room is double aspect and we're saving up to get all the windows replaced (they're old and leaky) so she gets especially cold. She also suffers from Raynaud's so she really struggles with her hands if she gets cold.
We haven't lit our log burner downstairs yet though. We don't have central heating downstairs, just the log burner. It makes everything lovely and warm, plus it looks cosy, but it's not cold enough for it yet.
