Hi all, I'm a FTM and absolutely have no idea what I'm doing re: temperature control for my 14 day old baby. I find he's either too hot and fussy or too cold and fidgety. I've got a growegg which is forever glowing red to denote our room is too warm. We're in a new build so all the rooms are stiflingly warm. Had a visit from the HV today and she said to give baby plenty of fresh air (I've had him closeted indoors because I'm petrified he'll catch a cold) and to open a window or two when he's asleep. It's 18 degrees where we are tonight. Me and baby cosleep. He's currently wearing a vest and a babygrow and I've covered him with a cellular blanket. Would it be okay to leave the window open tonight? Or would it be too cold? Will he catch a cold? Please help. I come from a culture where babies are covered under heavy blankets and duvets and anything less than that (in any weather) is akin to child abuse!
