I have a 4 month old right now and I'm a bit concerned with the constant temp in the house. my sister in law lives with us which she should be imo as she is 45 with a 17 year old son (we live at my father in laws until we get on our feet and he pays the electricity bill even though we have tried to pay, just an fyi) and the sister is throwing a bitch fit about the temp going too low and the bill going to high blah blah and told everyone not to put the temp below 78 and then even put a note above saying no lower than 78. kinda childish well she's been turning it to 79 sometime 80 degrees or shell juat straight turn it off and I've been sweating it's too hot, so I know baby gets hot I live in the central valley of California so it gets high 90s into the 100s so what is a good temperature for a baby so I can throw that in her face
