Heating house

Kyra • Heart warrior mama of baby boy born 27 June 2019 💙💙💙

It’s currently 12C (53F) outside and we have a split system in the lounge room where we’ve heated it to 22c (72F) to sleep with baby.

I’m wanting to start sleeping back in my room but to do that with the layout of my house we would have to heat the entire house as that section can’t be closed off.

Any advice suggestions?
